Nikon D7100 review

24 megapixels, no low-pass filter, 51 auto-focus points will make this a great camera for underwater photography

By Scott Gietler




Nikon had a winner with the popular Nikon D80 back in 2006, and they followed it up with even better models such as the D300, D90, D300s, and D7000. Many photographers purchasing their first dSLR purchased one of these models, and have been patiently waiting for a good reason to upgrade. Many photographers spoke about “waiting for the D400”, but the time of waiting may end for some.

Nikon has put its best sensor and best auto-focus system into the D7100, and appears to have merged the D70/D80/D90 and the D200/D300 lineups. With 24 megapixels, the body of the Nikon D600, the latest CMOS sensor with Expeed 3 processing, and additional video enhancements, the D7100 is poised to set the new standard for cropped sensor dSLRs.

In this Nikon D7100 review we will cover:

  • Key specs and features
  • Body and Handling
  • High ISO tests
  • Detail compared with the D7000
  • Auto-focus speed tests
  • Sample images
  • D7100 Underwater housings (jump to housing reviews)
  • Recommended Lenses & Strobes
  • Conclusions


Key Nikon D7100 specs:

  • 24 megapixels, vs 16 megapixels on the D7000
  • 6000 x 4000 pixels
  • 1/250 sync speed, 1/320th in auto-fp mode; flash recycles quickly
  • Removal of the low-pass filter means sharper images, more detail and 100% crop (assuming the image is in focus and the lens can resolve that much detail)
  • 51 Auto-focus points, versus 39 on the D7000. The Nikon D300 and D300s have much better auto-focus capability than the D7000. The D7100 improves upon the excellent D300 auto-focus.  Macro photographers will see a nice improvement.
  • 1.3 crop factor for stills & video - this is really nice, especially when you want less angle of view than your lens delivers.  For example, when using the Tokina 10-17mm fisheye or for wildlife videography
  • AUTO-ISO capability has been improved. This is huge for topside action and ambient light photography, because you can program the camera to react quicker to changing light conditions.
  • SPOT white balance in live view mode - this could be great for underwater video, You can choose the spot on the screen you want to use for white-balancing. This will make white-balancing for many more much more convenient and accurate, especially for video.
  • Dual SD card slots
  • 1080p video, up to 60fps, MPEG-4 and H.264 format
  • Ultralong battery life, CIPA rated to 950 shots

The D7100 also has some nice features such as:

  • Uncompressed HDMI video output
  • LCD size of 3.2 inches (versus 3 inches on the D7000)


Availability: Now
Price: $1200 body, $1600 with 18-105mm lens


Jump to Underwater Housings for the D7100


Nikon D7100 1.3x crop mode

The 1.3x crop mode of the Nikon D7100 is poised to be a very useful feature of this camera, for times you wish your lens wasn't so wide, or that you had more reach.

You basicaly see a cropped portion of the sensor in the viewfinder, giving you the equivalent field of view of a 1.3x version of the lens. So instead of shooting with a 10-17mm fisheye lens underwater, it will be like shooting with a 13-22mm lens. Instead of shooting with a 60mm lens, it will be like using a 78mm lens. For wildlife photography, shooting at 400mm will now be like shooting at 520mm.

The autofocus and exposure will be acting on the cropped portion of the lens. You'll be able to compose your picture more easily. You'll only have 15 megapixels instead of 24 megapixels, but who cares? 15 megapixels is still a huge number.

Also, when used in 1.3x crop mode, your D7100 can take photos at a rate of 7 frames per second, a nice bump the 5fps offered by the Nikon D7000.


NIkon D7100 auto ISO mode

Auto ISO is an excellent feature that more photographers should use. It basically tells your camera to boost the ISO until desired shutter speed was reached. The problem was, previously, if you are using a zoom lens, you always need a faster shutter speeds for longer focal lengths. The Nikon D7100 has added some functionality to address this issue.

I find auto ISO mode indispensible for wildlife photography. For example, for hummingbirds, I set a minimum shutter speed of 1/800th. The camera will automatically raise the ISO until this shutter speed is achieved, up to whatever maximum ISO that I set. Magic!

Fitting the D7100 into the D7000 / D600 underwater housings

The dimensions of the D7100 are very, very close to the D7000. However, several buttons and key contols are placed in different positions.  You can see the comparison photos here. Still, the aperture & shutter speed dials and the shutter release look to be in the same positon, so it is possible that you could get very basic functionality of the D7100 in some of the D7000 underwater housings. But the camera tray will probably give you some difficulty in attaching.

It is much easier to fit the D7100 into a D600 housing. We were able to fit the D7100 into a Nauticam D600 housing, and the many of the key controls like image review, aperture/shutter speed dials, and the shutter worked.


Nikon D7100 underwater housings

Ikelite and Nauticam both have D7100 housings out, and we expct Aquatica, Sea & Sea, and Hugyfot soon. The Ikelite D7100 housing will be shipping around April 19th, and is the best value at $1,500, and will also have their excellent TTL capability built into the housing. You can watch the Nauticam D7100 housing product video. We expect the Sea & Sea D7100 housing, and Aquatica D7100 housing will have similar excellent ergonomics as their D800 housings have (both housings will be ready in early July), and the Hugyfot will have their Hugycheck vacuum-check system built in to the housing.

Adobe Lightroom support for the Nikon D7100 & a hack

So you want to open up your Nikon D7100 files in Adobe lightroom? Adobe Lightroom does not yet support the Nikon D7100 raw files, but there is a great hack listed here that works great. It basically fools lightroom into thinking that the photo came from a Nikon D5200, which pretty much has an identical sensor.


Nikon D7100 - detail compared with the D7000


In my real-world shots taken with the D7000 and the D7100, I found that it was difficult to notice a large improvement in the details of the 100% crop. I up-resized the D7000 files so they would be the same number of pixels across as the D7100 files, which I thought was a more fair comparison. For certain subjects, I did notice more detail in the D7100 files, but it was not across the board. I did the tests with the Nikon 60mm F2.8 lens because of its excellent resolution.

Nikon D7100 high ISO tests

The D7100 appears to be just as good as the D7000 at high ISO, even though it has a smaller pixel size, which means decent to good images at ISO 3200 and ISO 6400. If you're looking to shoot with very high ISOs, you may want to be shooting with the D600, D800 or Canon 5D Mark III.

I am very, very happy with the high ISO performance of this camera, as I was with the D7000. I shot the D7000 at ISO 6400, and took the same shots with the D7100 at ISO 6400, leaving the high ISO noise reduction to normal. I then downsized the D7100 jpegs to be the same size as the D7000 jpegs, which I thought was a more fair comparison. I could not see any significant difference between the 100% crops of these shots.  See the sample images below.

Nikon D7100 auto-focus speed tests

The Nikon D7100 camera has an improved auto-focus system, with 51 auto-focus points, and better low-light capability in the center of the sensor. But how does this translate into the real world?

I tested the auto-focus between the D7000 and the D7100 in low-light, with various lenses including the 60mm, 60mm + 1.4x teleconverter, 18-200mm VR, and the 200-400mm VR. Across the board, I noticed faster auto-focus and less hunting with the D7100, especially when using a teleconverter. This was a welcome discovery because I did feel that my camera’s auto-focus took a step backwards when I switched from the D300 to the D7000.

I also did some night photography with the Nikon D7100 and the 18-200mm lens. I had a sola 800 red light focusing on the subject (a hummingbird moth), and the camera focused quite well. You can see the images in the sample image section.



Best Nikon D7100 lenses, topside

For landscape photography, I like the Nikon 10-24mm, or the Sigma 10-20mm – depending on your budget.

For wildlife photography, the 80-400mm VR will be a staple for most people. If you have the budget, the 200-400 F4 VR lens is excellent for wildlife with a great bokeh, and older versions of the 300mm F4 or 300mm F2.8 should also be checked out if quality of shots is more important than flexibility.

For portraits, picking up an inexpensive 50mm F1.8 lens is a must.

For general purpose travel, you can use the 18-135mm kit lens, although I prefer the extended reach of the 18-200mm VR.

People who want to cover indoor events or do street photography will probably want to pick up a fast F4 or F2.8 zoom lens in the 16-35, 17-55, or 24-70 range.


Best strobes

The Sea & Sea YS-D1 strobes would be the go-to strobe for most people, due it is amazing power and small size. A second contender would be the Ikelite DS-160 strobe, with its superior recycle rates, great color temp for wide-angle, and the ability to do TTL with any housing with the optional Ikelite TTL converter cable. Its only downside is the much larger size and weight vs the YS-D1, and its proprietary battery back vs the 4AA batteries of the YS-D1. Learn more about strobe positioning underwater.


Nikon D7100 compared with past models

Photographers upgrading from a compact or mirrorless camera are in for a pleasant surprise if they upgrade to the Nikon D7100. Owners of previous Nikon dSLRs like the D80, D200 or D300 will enjoy the additional detail in their photos, high ISO capability, and low-light auto-focus speed. D7000 users probably have less of a reason to upgrade, as detail and ISO performance are similar, although the auto-focus improvements are very nice.


Which underwater photographers should get the D7100?

We expect the NIkon D7100 to be the top choice for new underwater photographers looking to upgrade to a dSLR. People who especially love macro may want to upgrade their older Nikon to the D7100. And it will certainly tempt some macro photographers who had been previously looking the at the Nikon D800.

Underwater photographers focused on wide-angle will find the D7100 an excellent choice, although they may also be looking at the Canon 5D Mark III or the NIkon D600 for improved dynamic range.


Nikon D7100 concerns

With 24 megapixels on a DX size sensor, the pixel size is getting small. This is equivalent to 54 megapixels on a full-frame sensor (24 x 1.5 x 1.5). The main concern with small pixel size is the dynamic range being recorded by the sensor - especially for the wide-angle underwater photographer. High ISO noise had been a concern, but as you can see in the above tests, the Nikon D7100 high ISO performance looks quite good. We'll be doing some dynamic range testing soon.


Nikon D7100 conclusions

So far - we really like the camera, it feels very similar to the D7000, yet has a little better resolution, a little better focusing, and some other nice features that make it a nice upgrade for people shooting a D200 or D300 / D300s, or a great choice for first time dSLR users.

The D7100 again raises the bar for cropped sensor dSLRs, with its excellent low light auto-focus capabilities, excellent picture quality at ISO 6400, and the largest number of megapixels of any DX format camera. It is possibly the best choice out there on the market for serious amateurs, and we anxiously await Canon’s response. For underwater photography, the D7100 will serve the needs of most serious hobbyists, and many professionals who don’t need the increased sensor size and cost of a full-frame camera.

Canon 5D Mark III Review

Todd Winner
A Review of the Canon 5D Mark III from the perspective of an underwater photographer

Canon 5D Mark III Review

A first look at the Canon 5D Mark III from the perspective of an underwater photographer

By Todd Winner





Initial Thoughts

I've been shooting with the Canon 5D Mark III for the past few weeks and I have to say that I am extremely impressed with the camera. This is simply a fun camera to shoot with. I've been shooting with a Canon 7D for the past couple of years and the 5D Mark III really feels like a full-frame version of the 7D. The button layout is almost identical except for a few changes. The body is solid and well-built and is exactly what you would expect from a professional camera. It's incredible in low light with a native ISO range of 100-25600 and an expanded range all the way to ISO 102400! With that, you can practically shoot in the dark.

Borrowing the auto focus from Canon's flagship EOS-1D X, the 5D Mark III shares the newly designed 61-Point High Density Reticular AF. I have only briefly explored the AF capabilities, but it has performed well both in low light and fast action. The 5D Mark III now has a dedicated auto focus menu tab, making it faster and easier to get to the sophisticated auto focus system. With up to 6 fps continuous shooting, it is fast enough to shoot most anything you put in front of it. The images off the 22.3 megapixel full frame CMOS sensor are clean and punchy with excellent color across the ISO range. The 14-bit A/D conversion along with the next generation DIGIC 5+ Image Processor delivers stunning processing speed while keeping noise to a minimum.

Shooting Video

Video has been greatly improved over older Canon models. We now gain better low light performance and cleaner images, which is perfect for underwater ambient light footage.  The moire and alias problems have also been fixed from the older models. The 5D III offers an all-i frame codec which should offer better results for fast motion and also hold up better in post-production. Plus, the camera has a dedicated headphone output and the ability to adjust audio levels manually.


Testing The Mark III In The Bahamas

I had the opportunity to shoot with the new Nauticam NA-5DMKIII in the Bahamas last week with both the Canon EF 8-15mm f/4L fisheye and the EF 16-35mm f/2.8L II. The housing feels very similar to my Nauticam 7D, so it was easy to adjust to. I love the feel of the new aperture and shutter speed knobs. They're very easy to spin with just your fingertips and work well with gloves on. Instead of having all push buttons, they have designed levers for some of the more frequently used controls, such as the image review and ISO buttons. This is a truly outstanding feature, and the ISO lever is particularly useful when shooting video to adjust manual exposers.

The Canon 5D Mark III also comes equipped with a CF and SD card slot. I loaded up the SD slot with one of the new Eye-Fi Pro X2 cards and programmed the camera to write small jpegs to it. Although the Eye-Fi card cannot transmit wirelessly from underwater, as soon as I came up, I had images to review on my iPad. How cool is that?!  

Tiger Beach in the Bahamas is always a great destination for sharks and dolphins. You can read more here about diving Tiger Beach.


Canon 5D Mark III lenses for underwater

Canon 5D Mark III Wide-angle

For wide angle, my two favorite lenses are the EF 8-15mm f4L fisheye and the EF 16-35mm f2.8L II.  The 8-15mm gives you either a full frame fisheye at the 15mm end or a circular fisheye at the 8mm end. The lens focuses incredibly close and can be used behind a mini dome.  By adding a 20mm extension ring and a Kenko 1.4 teleconverter, you can increase the versatility of this lens giving you a similar focal length to the Tokina 10-17mm on a cropped sensor camera.  Mini domes work great with fisheyes for the majority of shooting but if you want the most from your split shots use a larger dome like a 8” or 9”. Read our Canon 8-15mm fisheye lens review.

The Canon 16-35mm is a fast rectilinear lens with a good zoom range.  It is nice for shooting wrecks and other subjects that have straight lines as well as subject that require the longer reach of the 35mm range.  Rectilinear lens require a large dome like a 8” or 9”.  I have been using the 16-35mm without a diopter on a 8”, with good results.  The 17-40mm is very similar in image quality to the 16-35 at smaller apertures.  It is a nice alternative for about half the price. Read more about dome port optics to understand dome port size and the need for diopters.

Canon 5D Mark III Macro

For macro, my lens of choice is the EF 100mm f2.8L IS.  It focuses very fast and is incredibly sharp. It has a reproduction ratio of 1x1 but I like using a flip dioper with the subsee +5 and +10 diopters when more magnification is needed.

Canon 5D Mark III underwater settings


  • Set your image quality to RAW.
  • I shoot almost all of my images with manual exposure settings so ISO, shutter speed and aperture are going to be based off of the scene. I always recommend using the lowest ISO that will give your desired shutter and aperture.  There have been a number of test that show Canon sensors being cleaner (less noise) at ISO 160 and multiples of 160 over the other ISO settings.  I typically try and use 160, 320, 640, etc over the other settings.
  • Having both a CF and SD card loaded in the camera, I use the CF card as my main recording and playback and set the SD to auto switch when the CF is full.  Using the SD card inserted in the camera does slow down the write speed to the CF card a bit but I don't notice the drop in speed being a big issue.
  • Picture style does not effect RAW images.  It does however change the way the JPEG preview images look on the back of the camera's LCD screen and they do get burned into your video footage.  I usually use the neutral setting.  This gives a somewhat flat looking image on the back of the camera but the histogram is probably closer to the RAW file and I'm going to be editing color, contrast and sharpness in post anyway.
  • I use auto white balance a lot on the 5D Mark III.  The camera is very good at getting the setting right.  White balance also gets burned into the video footage so it's important to get it right in camera.  Unfortunately, when shooting video, the auto white balance can change as you pan across a scene.  For video, I typically use the kelvin adjustments.  I also turn off or disable highlight priority and lens aberration correction.
  • The last setting I would suggest if you have a control on your housing is to use back button focus.  With back button focus you use a dedicated button to auto focus with your thumb.  You disable the auto focus from the shutter button in the custom controls menu.  Now I can start and stop auto focus independently from shutter release.  This can be very useful for pre-focusing action shots and off center compositions.  You can of course move your focus points to other areas in the frame but I find back button focus a more effective technique once you get use to it.

So, should you upgrade? If you're after exceptional image quality and performance, this is a great camera to consider. However, the list price of $3499 USD will keep it out of reach for many. The 5D Mark II is still available at a much lower cost and offers similar image quality, but lacks the sophisticated auto focus and other improvements. The 7D is about half the cost of the 5D Mark III and offers excellent auto focus and frame rates, but not the same image quality of the 5D. If you are shooting with any of the other APS-C dSLRs you will see improvements in all areas. If it's in your price range, especially if you are already invested in EOS full frame lenses, you will not be disappointed by this camera.

Initial Thoughts on the Olympus PEN E-PL5 & XZ2 Cameras

Kelli Dickinson
A brief review of the Olympus PEN E-PL5 and XZ-2 cameras, as released after the Photokina show

Initial Thoughts on the New Olympus PEN  E-PL5 & XZ-2 Cameras

By Kelli Dickinson



Olympus just released a whole new group of cameras after the Photokina show in Germany. Among these are newer models of several popular underwater cameras. These include the new PEN E-PL5, PEN E-PM2 and compact Olympus XZ-2. Did Olympus make enough changes to these new cameras to make them a better choice than their predessor? Here are our initial thoughts: 


Olympus PEN E-PL5


The new Olympus PEN E-PL5 boasts an new 16 megapixel sensor, a nice improvement over the E-PL3's 12. In addition, the continuous shooting mode has been increased to a very fast 8 frames per second, but just like with previous models, both focus and exposure are locked based on the first frame. 

As always, the new Olympus E-PL5 claims to have faster auto-focus with a new high speed imager system… which we have tested, and it is quite fast. The camera comes with the same 14-42mm IIR kit lens as previous models, and includes all the same controls and features as the previous cameras. ISO capability has been increased to 25,600, but how the camera handles at higher ISO's compared to previous models still needs to be tested. 

The new E-PL5 brings back the good old .MOV recording format, meaning all you Mac users can shoot and edit video again as it saves with the option of H.264 compressor or  AVCHD system. 

Great additions for topside shooting include touch screen capabilities and a new LCD screen that can flip 180º up so you can see the screen from the front of the camera, (does not go all the way up when the flash is attached). 

In general, I think the E-PL5 will be a great step up from the previous PEN models. It will be the best option if you're looking for a high quality mirror less camera in a good quality housing that won’t break the bank. As always it uses the micro-four thirds mount, so all the lenses like the new 60mm macro, Panasonic 8mm fisheye and more will work great with this camera underwater!

Compared to the Olympus OM-D

The Olympus OM-D E-M5 costs $400 more, and comes with an electronic viewfinder, excellent 5-axis image stabilization, and 2 control dials - none of which the E-PL5 has. Choosing one of these great cameras will be a tough decision!

In this 100% crop of the mural, we see stunning detail.  Nice EPL-5!

Olympus E-PL5 Underwater Housing

The housing for this camera has not been released yet, but we believe it will follow in the tradition of Olympus' high quality polycarbonate housings which offer full control of the camera, and the ability to change out the port to support a dome for wide angle lenses. 


PEN "Mini" E-PM2

Unfortunately, while some good improvements have been made in the new PEN Mini over the original model, we have been told that Olympus will not be making a housing for this camera. Happy users of the E-PM1 looking to upgrade should look at the new E-PL5.


Olympus Stylus XZ-2

The XZ-2 seems to be just the next step in a solid line of compact cameras. The new camera includes new 12 MP CMOS sensor, upgraded from  the XZ-1's 10MP CCD. This new sensor claims to produce images with less noise and more detail. The XZ-2 also shoots full HD video but now the recording format is the better .MOV that works on both Mac and PC systems, with H.264 or MPEG-4AVC compression, versus the Motion JPEG format for the XZ1. Other important features remain the same as the XZ-1 with the same fast and bright 1.8 iZuiko lens and 4x optical zoom. Low light capability is still great because of this fast lens, and good ISO handling. 

One really nice improvement lies with the front control ring around the lens. In the XZ-1 this ring was limited to only the primary function based on what mode you were in (aperture control in A Mode, Shutter control in S mode). The new XZ-2 offers more flexibility with customizable functions, giving you direct access to the most important setting including ISO, aperture and shutter speed. In addition the ring can also be used to zoom and focus.

For topside, Olympus continued its general camera evolution by including touch screen functions and a swivel / tilt LCD screen. The hot-shoe acts as an accessory port to attach different flashes, an electronic viewfinder, microphones etc. 

The XZ-2 looks to be a basic evolution of the XZ line with increased megapixel count, better recording format and improved control for important camera functions. We recommend the new Sony RX100 or Canon G12 for compact options over the XZ2. 


XZ-2 Housing

While this has not been released yet, we believe the housing will offer full control of the camera like the XZ-1 and hopefully include the ever helpful 67mm threads, great for adding accessory macro and wide angle lenses.

The new Canon S110 and Canon G15 specs, comparison, and mini-review

Canon S110 and Canon G15 cameras announced

Revolutionary or Evolutionary? Read on to find out

By Scott Gietler



The Canon S100 and Canon G12 are two of the most popular cameras on the market for underwater photography. How will their replacements, the Canon S110 and Canon G15 stack up?  Manufacturers often make "improvements" that have unintended consequences for underwater photography.


Canon S110 - basically the same as the Canon S100

No big news here - Canon took the S100, took away the built-in GPS, and added wi-fi. The controls are the same, but the body was changed ever so slightly - probably just enough to make the metal S100 housings not work with the S110. We'll post the test results as soon as we get an S110 in-house. 

canon g15 review for underwater photography
Canon G15


Canon G15 - revolutionary F1.8 - F2.8 lens

The new Canon G15 has a new, very bright F1.8 - F2.8 lens. The Canon G1X was a disaster for underwater photography because it lacked the ability to take close-up photos. We'll be anxious to see how the new lens on the G15 performs. 

The Canon G12 is one of our two favorite compact cameras (the Sony RX-100 is the other), hopefully Canon didn't restrict the macro capability of the Canon G15 too much, and the G15 can take the G12's spot. According to the official specs on the Canon website, the macro capability on the G15 is the same as the G12.


Canon G12, Canon G15 differences:

  • Canon G15 has a much brighter lens (both cameras have a 28-140mm lens), which will have some great benefits for indoor and ambient light photography, including the ability to blur the background when zoomed in to 140mm. The Canon G12 lens has a F2.8/4.5 aperture.
  • 12 megapixels instead of 10
  • Canon is claiming faster auto-focus. We will have to wait and see!
  • Canon G15 is slightly smaller
  • Full HD 1080p video recording; lens can zoom & focus while recording
  • Offers an HDR mode
  • Upgraded CMOS sensor
  • ISO dial has disappeared
  • No more articulating LCD screen
  • Retail price of $499


Initial thoughts on the Canon G15 and S110

It appears that the Canon S110 and Canon G15 will continue to be solid choices for underwater photography, with great macro and wide-angle wet lens capability, but with increased competition from the Sony RX-100. We'll continue to update this article once we handle the cameras ourselves.

Update: Nov 23th 2012 - our partner Bluewater Photo has just posted a Canon G15 quick review for underwater photography


Canon G15, S110 underwater housings

  • Ikelite, Nauticam and Recsea have underwater housings for the Canon S110; all 3 housings support wide-angle and macro wet lenses
  • Ikelite and Recsea have released Canon G15 housings; both housings support macro lenses, only the Recsea housing supports a fisheye lens

Olympus OM-D E-M5 Camera Review

Kelli Dickinson
An underwater photographer's review of the new Olympus OM-D E-M5 mirrorless camera.

Olympus OM-D E-M5 Camera Review

By Kelli Dickinson





The Olympus OM-D E-M5 camera sets a new standard in the mirrorless camera line with improvements that make the gap between the mirrorless cameras and entry level dSLRs even smaller. 

Overall easy to use, this camera has a little something for everyone with Olympus' standard set of auto functions, art, and scene modes. For the more advanced user, the OM-D really shines. Improvements in focus speed, image processing, flash sync speed, and more make the E-M5 a great choice if you're looking to take your photography to the next level. 


E-M5 Specifications

  • 16 MP, 4608 x 3456 max resolution
  • Micro-Four Thirds CMOS sensor (17.3 x 13mm)
  • ISO 200 - 25600
  • Electronic Viewfinder with 100% coverage
  • 3" LCD Tiltable screen
  • Touchscreen capabilities
  • Micro Four-Thirds mount with a wide variety of lenses
  • Minimum Shutter speed 60 sec, max shutter speed 1/ 4000th
  • Accessory flash sync speed 1/ 250
  • Video recording at 1080i 60 (1920 x 1080 resolution) 
  • Extensive weather proofing


Body Style



The E-M5 harkens back to Olympus' OM-D style SLR film cameras. A retro-styled body sets this camera apart from the previous mirrorless cameras from Olympus and other manufacturers. Still maintaining a small size, it offers dSLR-like controls through two control dials. These dials are well placed, making them easy to use for quick setting adjustments. 



Unlike the other Olympus PEN models that have geared toward a more streamlined, compact look with fewer buttons, the EM-5 features a standard array of buttons, a large mode dial and two customizable function buttons. The only downside I have found is that the standard array of buttons on the small sized body results in small buttons which could be more difficult to control with larger hands. 

In addition, Olympus did not include a pop-up flash, but continued with the accessory flash that attaches to the hot-shoe on the camera like the latest PEN models. While this can be nice, as you only have to have the flash when you need it for shooting, when coupled with the bump from the new Electronic Viewfinder the flash can make the camera seem a bit top heavy. 



Changes from previous Olympus mirrorless cameras

The previous PEN mirrorless cameras moved from a more classic design to a streamlined look over the years, but the E-M5 brings back the classic lines. The E-M5 has a 16MP sensor vs 12MP, which is much better at handling high ISOs. The E-M5 also has control dials for changing settings, where as all PEN models have used buttons or a single wheel on the back of the camera. The E-M5 includes a tilting screen like the previous model (E-PL3) has, but this LCD is larger at 3" and includes touch screen capabilities. 



Electronic Viewfinder and LCD


One major improvement in the camera design is the addition of an electronic viewfinder. This viewfinder offers 100% coverage of the image. The viewfinder is clear and bright, offering a great alternative to shooting though the LCD screen. While using the electronic viewfinder, the LCD displays the important quick functions in a "Super Control Panel," allowing for easy and fast setting adjustments. A proximity sensor turns off the LCD when you bring the camera up to your face, saving battery life and your eyes. If you prefer shooting through the LCD, that is still easily accessible through the touch of a button. Live view disables the Super Control Panel, and those functions are brought up by pressing the OK button, just like with other Olympus models. If you like the look of the SCP, you can change the setting in the camera so that the SCP appears in the viewfinder by pressing the "OK" followed by the "Info" button. When using the camera in a housing, you can easily disable the automatic switch on the Live View and the EVF, allowing you to switch between the two simply by pushing the button on the camera (accessible with both Olympus and Nauticam housings).


ISO Image Tests

The E-M5 includes Olympus' Micro-Four Thirds CMOS sensor and has a 16MP resolution. Olympus has really made improvements in the low light sensitivity of the E-M5, which has ISO capability starting at 200 and going up to 25,600. The E-M5 performs well at higher ISO's than previous mirrorless models. 


At ISO 1600


At ISO 3200


At ISO 6400


At ISO 12800


At ISO 25600


Image Stabilization

In addition, Olympus has completely re-designed the built-in image stabilization on the E-M5. The new multi-directional image stabilization system offers stabilization over multiple axes. This allows for better performance and ease of shooting in low-light situations. 


This image was shot with the IS turned off at 1/20 F13.


This image was shot with the IS turned on at 1/20 F13.


Focus and Speed

The E-M5 improves the focus speed from previous Olympus cameras, and it holds up against other cameras on the market such as the Sony NEX series and Panasonic cameras (though the GX1 did beat out the E-M5 by fractions of a second during some of our tests). 

The E-M5 blew away all of the competition with a much faster burst mode, which shoots images at up to 9 frames per second without flash. One thing I did notice is that while shooting continuously and panning the camera, the focus does not hold as well as some higher-end dSLR cameras. 



The E-M5 ships with a choice of lenses. The first option is the standard 14-42mm kit lens that you find in their previous cameras. This lens works well for macro, focusing down to an image 3" across alone, and up to 1 3/4" when you add a Dyron 67mm macro diopter. This is great macro for a kit lens in general, though for an added bump you can upgrade to the new 12-50mm lens, which includes electronic zoom and a macro focus switch.

This lens is great. There are three modes on the lens, which are switched by sliding the zoom ring forward or back. Two relate to zoom control, electronic or manual, but the third locks the lens at 43mm and switches it into a macro mode. The macro mode is really what makes this lens a great choice over the less expensive standard kit lens for underwater photography. The macro function on the lens brings the focus down from a photo about 3.5" across to 1.25" across, which is fabulous for macro shooting. Add on a Dyron +7 macro diopter and you can get focus on an image less than one inch across. Nauticam will be releasing a port with control of this lens, though Olympus has not announced if it will support the lens in the housing. 



The E-M5 shoots full 1080i 60 video with the H.264 HD compression that is found on many recent cameras. One major improvement over the previous PEN models is that Olympus has moved away from the AVCHD file storage format, which moved all video files into a well-hidden separate file. The E-M5 saves the files as .MOV files in the same folder as your images. In addition, you can also shoot in a motion .jpeg mode. 

Movie recording can occur from any still picture mode by simply pressing the red record button on the top of the camera. If you prefer something different, this function is customizable to any button through the custom menu system, so you can move the record function to another button for smoother video starts. 

One small downside is that if you do start shooting a video from any of the still picture modes, the camera automatically sets to Program mode, controlling the aperture, shutter speed and ISO. The focus mode will revert to whichever mode you had set when last in video (note: the default is continuous autofocus). In order to take control over your video settings the camera must be switched to the dedicated video mode.

With the focus improvements overall on the camera, the continuous autofocus has improved some with the new E-M5, however it is still noticeable because the camera hunts a tiny bit due to the contrast-detection autofocus system. However, while underwater the lag between the camera automatically adjusting the focus on Continuous autofocus is very noticeable and too slow to be of much use. I recommend using Single autofocus, and gently pressing the shutter button halfway down to re-focus. This focus is instantaneous with very little hunting (as you can see in the video below). 


Sample Underwater Video (taken with the 14-42mm kit lens)


One large improvement for video is the improved image stabilization built into the camera. The multi-axis mechanical image stabilization that the E-M5 was designed with really shines in video. Due to the multiple axis stabilization, Olympus boasts that it can cope with both the different types of movement caused by hand shake and by walking at the same time. To test this, I took two videos with the camera while walking down the street holding the camera in one hand. Take a look at the results below. 


Image Stabilization test video




Overall I have been very impressed with the E-M5. It is a big improvement from the current PEN series of cameras from Olympus and other micro four-thirds cameras on the market. Image handling and quality compares to that of the larger sensor NEX series of mirrorless cameras, and the design is well thought out. The dual dials for settings control are great and the return of an electronic viewfinder is will make many people very happy. Video quality is good, but if you are very serious about wanting stellar video I would say to look at the NEX-5n or NEX-7 which offer more options and control on video recording. 


Using the OM-D E-M5 Underwater

The E-M5 works fabulously underwater. I have been able to test out two of the housings options, Olympus and Nauticam. Both housings allow full functionality of the camera. Underwater the E-M5 still focuses quickly and accurately, which is even improved with the use of a focus light. The faster sync speed of 1/250 is great for both macro and wide-angle shots, allowing more creative lighting by stopping down to bring out black backgrounds in macro shooting and more control on the ambient light with wide-angle.


Underwater Housing Options

Nauticam Housing

The NA-EM5 housing fits the camera like a glove and is designed extremely well so that it is easy to use, and changing functions in the camera is a breeze. The housing is made out of machined aluminum with a good grip that makes holding onto the housing and taking pictures easy and very comfortable. Buttons mirroring the camera are organized on the housing in a way to make it easy to access and control underwater, even when wearing gloves. Nauticam placed the two control dials nicely so that you can easily adjust both without letting go of the housing, or your handle. 


Nauticam Housing Specs

  • Machined aluminum, nicely sized with a good grip, and well-placed buttons.
  • Includes Nauticam's classic port release system, making port changes quick and easy.
  • Zoom control is easy to turn with one finger, and works well with gloves.
  • All buttons are tiered for ease of use underwater.
  • Aperture and shutter speed buttons are easy to turn and well placed for easy manipulation and quick setting changes.
  • Viewfinder control button allows switching between the LCD and EVF (need to turn off the automatic LV sensor).
  • Included moisture detection system.
  • LCD window is large, and allows easy viewing of the LCD, which is tilted for an optimal viewing angle.
  • The EVF window has slight magnification, making it easy to view the full viewfinder.
  • Housing is designed for flash to be popped up, so there is no need to change the camera settings for UW mode (allowing for customization of the both of the Fn buttons).
  • Shutter is firm and easy to use - easy to get half-shutter focus.
  • Video record is a lever, easy to activate while keeping hand on housing and making it much easier to limit any shake at the beginning of the video.
  • Includes hot shoe mount and fiber optic ports (S&S and inon style).
  • Includes a bulkhead port for an optional bulkhead so that you can use sync cables from the hot shoe on the camera.
  • A wide variety of ports is available for both Olympus and Panasonic's Micro 4/3rds lenses.


Olympus Housing



The Olympus PT-EP08 continues in the style of previous Olympus housings, with the black polycarbonate body and red front on the port. One big improvement is an updated port system which allows for easy port changing. However at this time, Olympus has not confirmed if they will be creating new ports to fit the variety of lenses available for the E-M5. Right now they only have the port for the 14-42mm kit lens. The buttons are large and easy to manipulate, even in gloves. 


Olympus Housing Specs

  • Polycarbonate housing, clear backplate allowing some view into the o-ring with a good front grip.
  • Shutter lever is precise and easy to get half-shutter focus.
  • All the buttons are tiered, making it easy to use underwater, even in gloves.
  • Zoom control is placed well and easy to use with two fingers.
  • One downside: the aperture and shutter speed dials are not easily reached, and require moving the hand off the housing and using two fingers to turn.
  • Housing was designed to be more ergonomic, and to be used with the UW Mode activated so the flash will fire without being popped up. Unfortunately this also takes up one of the customizable Fn Buttons.
  • The location of the video start button required me to remove my hand from my handle, making smooth video starts difficult.
  • The port system was completely redesigned from previous housings, allowing quick and easy port changes, with a loud secure click on the locking mechanism.
  • Includes a hot shoe mount and 2 fiber optic ports.
  • Includes a button to switch between the EVF and LCD screen underwater.

Sony RX-100 review for underwater photography, including focus speed, wet lenses

Sony RX-100 Review

A new leader in compact camera choices for underwater photography

By Scott Gietler




The Sony RX-100 is an exciting option in the compact camera market. This very pocketable camera has become a staple for underwater use when paried with one of several RX-100 housings on the market. You can also check out our RX-100 M2 Review.


sony RX-100 review


sony rx-100 underwater photography underwater housings
The height and width of the RX-100 is almost the same as the small, stylish Canon S100 which Sony has "mimicked". It is slightly thicker than the S100. The front & rear control dials, and the function button are highly configurable - I reassigned the function button to ISO


Sony RX-100 - amazing specs

Here's the specs, and I think they speak for themselves. Quite amazing for a compact camera!

  • Large sensor, 3x the size of a Canon S100 / G12 sensor
  • 20 megapixels - very nice!
  • RAW, full manual controls, etc. (read more about Raw vs JPEG, and about why manual controls are important in underwater photography)
  • Electronic shutter allows for shooting with flash at high shutter speeds
  • Bright F1.8  28 to 100mm lens
  • 1080p 60fps video, full manual controls during video; movies look great
  • Controls are highly configurable
  • Very nice panorama and HDR modes
  • Great high ISO performance (reading about using ISO underwater)
  • $649 in the US


Great details in photos when pixel-peeping

100% crop of a Sony RX-100 photo, taken underwater. The full-size photo of the wine bottle can be seen just below this photo. Given that this is a 100% crop, the detail is amazing. You can see individual lines & dots of the half-tone printing style on this wine bottle very clearly, even the tiniest lines are not blurring together at all. The demarcation between the different colors is also very clean and crisp.


Sony RX-100 - great TTL in manual mode


Shooting the RX-100 camera underwater with YS-D1 strobes in TTL mode. See photo above for 100% crop of this photo.


We tested the RX-100 camera underwater with the new Sea & Sea YS-D1 strobe. The results were great, the exposures in manual mode were very good, and the YS-D1 exposure compensation dial worked very well. 


Sony RX-100 - great wet lens options

Performance with the Dyron +7 and Subsee +5 macro lenses was great, and we got amazing detail by stacking the Dyron +7 with the Subsee +5.

See the new Rx-100 wet lens test results


Photo taken with the Dyron +7 macro lens


Photo taken with Subsee +5 macro lens


Dyron and Subsee lenses stacked, very nice~


Macro tests on land

The macro performance is not as good as the Canon S95, S100 or G12 - but is more than acceptable with a wet diopter. 

  • No diopter - takes photo 3 inches across
  • With Subsee +5,  takes photo 2.3 inches across
  • With Dyron +7, takes photo 1.4 inches across
  • With Subsee +10, takes photo 1.4 inches across
  • Dyron +7 and Subsee +5, takes photo 1.06 inches across

Read more about the Subsee +10 diopter

Wide-angle wet lenses

This is one of the only compact cameras, other than the Canon S95, that has no vignetting with wet-mount fisheye lenses. Very nice!


No wide-angle lens used, camera at 28mm


Photo taken with Dyron fisheye lens, much wider!

Supermacro with the Nauticam housing, Subsee +10 diopter, great detail!

Sony RX-100 - tiny size, huge sensor

The RX-100 is about the same size as the Canon S95 or Canon S100, which means it is a truly pocketable camera. The sensor size is 3x the area of the Canon S100 or Canon G12 sensor, and about half the area as a mirrorless micro-four thirds camera sensor.


Sony RX-100 - focusing speed

Focusing speed is a little faster than other compact cameras like the Canon S100 or Canon G12. Some of our staff thought it focused significantly faster than other compacts. It is still not quite at the level of mirrorless cameras like the Olympus PEN, Panasonic GX1 or Sony NEX series.


Sony RX-100 - compared to S100, G12, Mirrorless cameras

If your main criteria is small size, great image quality, and good wet lens options, the RX-100 is the camera for you, if you don't mind spending a little more than you would for an S100 or G12 setup.

Mirrorless options from Olympus, Panasonic and Sony will be slightly larger, and cost more, but results with dedication macro and fisheye lenses will be better, and focusing will be faster.


Sony RX-100 battery life

The RX-100 is rated for 330 shots according to CIPA standards. This is much better than the 200 shots the Canon S95/S100 is rated for. The camera will last 2 entire dives underwater no problem, and may even last for 3 dives like the Canon G12 and the Sony NEX-5N does - but this will have to be tested.


Sony RX-100 flash recycle time

The RX-100 on land has an incredibly slow flash recycle time, especially on full power. So slow, in fact, that I thought this feature would kill the camera as an option for underwater photography. The camera has no hot shoe mount, so fiber optics must be used underwater to fire the strobe.

Luckily, the tests underwater with my Sea & Sea YS-D1 strobe were quite different. The camera flash recycled at an acceptable speed, and I was able to shoot at speeds in line with other compact cameras. Perhaps this is because the power of the YS-D1 strobe meant that the camera's internal flash didn't have to use as much power. The good news is - you are unlikely to miss an important shot. 


Sony RX-100 raw converter support

Adobe Lightroom now supports the RX-100 as of October 3rd 2012, so you no longer need to use Sony's raw converter, called Sony Image Data Converter.

Canon S100: In-Depth Thoughts And Housing Reviews

Everything you need to know about the Canon S100 camera and the best housings options on the market.

Canon S100: In-Depth Thoughts And Housing Reviews

Everything you need to know about the Canon S100 camera and the best housing options

By Victor Tang





As a frequent diver and underwater photographer, lately I have observed that more and more people who go underwater are equipped with some kind of camera. In fact, I'd say it's rare for a diver to go out without one. This might be because of the increasing affordability of the hobby, or perhaps because of the knowledge that the underwater world is deteriorating and the collective desire to archive its current beauty. Naturally, compact cameras make up the bulk of the market, and some premium options even come tantalizingly close to dSLRs in terms of image quality. Canon has always been at the forefront of producing amazing compacts for underwater photographers, and the new S100 model promises to build significantly on the popularity of its predecessor, the S95


The S100 is slightly bigger than the S95 but comes with more features and still fits easily in your hand.


My first impression of the Canon S100 when I took it for a spin in Tioman Island was very positive. The camera proved to be good at capturing fantastic shots with vivid colors and great detail. While selecting your camera is only half the battle, the next step is finding a housing, which we will discuss in-depth further down in this article. There are many housings on the market for the Canon S100 for different tastes and budgets. Remember that not all housings are created equal, and in this article I will evaluate the differences between the “budget” and “premium” options. I'll specifically be looking at the S100 housings from Ikelite, Fisheye FIX and Recsea.


The S100 Familiarized

Many articles have been made available with reviews and technical specifications for the S100, including my own “First Impressions” article here on the Underwater Photography Guide. After having more time to tinker with the camera, here are some important insights to be added:


  • For a compact of this size, the ergonomics have proven to be excellent. The dials for aperture and shutter are well placed, allowing single-handed operation should the need arise. Selecting ISO requires a single touch on the RING FUNC button and using the rear dial to achieve the desired setting. 
  • The increase in zoom range from 3.8X to 5X gives a camera of this size greater flexibility than compact users may be used to. Of even greater importance is achieving a field of view of 24mm at its widest setting. Underwater this gives an effective field of view of 30mm, which instead of 35mm of the S95 and G12, allows the photographer to get closer to the subject and illuminate it better when employing strobes
  • Video output from the S100, especially in low light, is excellent due to the wide f2.0 aperture at its widest setting. This is especially helpful for users who are shooting video without using video lights. Coupled with the close focusing distance of 3cm means the S100 is able to take video clips fairly sized (8cm/3inches or bigger) macro subjects without adding external enhancements like macro lenses.
  • ISO settings of up to 400 can be selected without much loss in image quality and fine detail. Having upgraded the S100 from a 10-megapixel sensor to the 12-megapixel one, image detail is more effectively retained. These two qualities are great for newly minted photographers who may not have external strobes to light up their photos. Advanced users taking ambient light photography will also appreciate these attributes. In short, this camera is more forgiving than ever before out of the box.


Of course, there are some less favorable things to note:


  • The Live View on the S100 can lag very considerably in low light conditions, and it takes awhile for the camera to catch back up once it starts to lag. Adding a focus light, even with is turned on at all times, does nothing to rectify the situation. I had the luxury of having two S100s to work with, and both gave me the same results, so this could be a firmware problem that I hope will be rectified on the upgrade.
  • The lens “breathes” when it's focusing, shifting back and forth to achieve focus. This may result in incorrect framing of the subject when it is in focus, meaning the subject as seen on the LCD could be bigger or smaller than what the photographer intended.
  • The autofocus absolutely rocks… when it works, that is. When the S100 is put through its paces underwater the autofocus takes longer to lock on as compared to on land. When it does lock on, the focus accuracy is perfect only 70% of the time. This issue is exacerbated when deploying macro lenses, so users who are used to focusing “within the ballpark” and relying on the camera’s autofocus to achieve final focus accuracy may find it harder to get the results desired. Even when moving the camera back and forth and relying on your eyes to get focus accuracy, upon half-shutter the autofocus may make the image even more out of focus than before. Using focus check is a must when taking macro subjects. A firmware upgrade may solve these problems, but for now users may have to put more effort into achieving the perfect shot. Of course, it has to be mentioned that when focus accuracy is achieved the contrast and details in the image are excellent.

S100 Housings: which one?

With a slew of underwater housings available, it's easy to get overwhelmed and become unsure which will be right for you. Each will allow for beautiful photos and of course keep your camera dry, but the devil is in the details as each manufacturer has different methods of allowing access to the camera controls.


Ikelite S100 Housing.


Canon actually markets their own underwater housing for the S100, but most buyers would opt to pay a little more to get the Ikelite offering. With a much tougher polycarbonate shell and better quality buttons and control levels compared to the dinky ones on the Canon housing, the Ikelite option will easily outlast your S100 and another one. Ikelite also manufactures their own accessories like external strobes and add-on lenses that integrate seamlessly with their housings, so there are no shortage of options should you want to take your photography further. With a maximum depth rating of 60 meters, the Ikelite housing is more than capable of operating within recreational dive limits, especially compared to the Canon housing's maximum depth of 40 meters. The Ikelite is a no-frills housing perfect for starting off your underwater photo adventures.

The Ikelite housing fits in the palm of your hand, with easy access to all the control buttons and levers. However, to use the control ring dial on the housing a plastic gear ring has to be installed on the front control ring itself. The gear ring is fairly tight and there have been cases where repeated dismantling and installing causes it to break, so if possible the gear ring should be left on the control ring. Setting the camera into the housing is a simple task of slotting the camera within the space marked out by the pylons and making sure the gear ring on the control ring on the S100 meshes solidly with the control ring dial on the housing. The lens port of the housing conveniently features a 67mm thread to allow the photographer to use “wet” macro and wide-angle lenses.

Of all the controls on an underwater housing, that which activates the shutter button is arguably the most important, for the mechanism has to be tactile enough for the user to feel the “half press” detent on the camera but still offer enough resistance to ensure the shutter is not inadvertently fully depressed. A well-engineered shutter control should allow the photographer to activate half shutter to see if the subject is in focus and also utilize features like focus check for further fine-tuning and take the shot only when the photographer chooses to. Ikelite has opted for the shutter lever where the movement to depressing the shutter is akin to pulling a trigger on a pistol. 


How the Ikelite shutter lever depresses the shutter button.


Using strobes takes a little extra preparation, as the Ikelite housing does not come equipped with any method to trigger external strobes for both sync cords and fiber optic cable. The easiest way to use strobes with this housing is via fiber optic cable, the common method being to stick on a velcro removable pad embedded with an open fiber optic cable end, right in front of the camera flash unit on the top right hand corner of the housing. A more elegant route is to paste a strobe mask set like those offered by Sea & Sea. The strobe mask set allows you to use dedicated fiber optic cables for underwater strobes and ensures a reliable activation of the strobes when needed. If the photographer has two strobes it is also a simple task to get a rubber bush offered by Inon and slot two open fiber optic cable ends through the bush on the housing.


A bit of DIY work but gets the job done.


Now that we're prepared let's take the housing underwater!


Through the paces

The S100 Ikelite housing with the camera inside feels slightly heavy in the water but not enough to warrant rethinking the weights one uses while diving. When attempting to turn the camera on you will realize how stiff the controls are on the housing. In fact, all the buttons on the housing, save for the shutter lever, are extremely stiff and it takes some effort to use the buttons to access features on the S100. 

Another issue occurs when trying to use the zoom dial. There is no return spring on the level to get the zoom lever back to its neural position after using it. Should the user forget to manually shift the dial back to its original position the zoom lever on the camera stays permanently on the zoom in or out, causing the S100 to freeze up. When the camera “freezes up,” using any control on the housing will illicit a non-response from the camera and the shutter button will not allow any picture to be taken. If this occurs underwater you will need to check your zoom dial.


The zoom lever (middle) stuck at zoom-in position. It needs to be rotated back manually.


The 67mm female threads are well made and screw in very comfortably. However, at shallow waters (5 meters and shallower) and in good light there is a some glare from the housing that may impede your view of the LCD screen. This problem becomes worse if the photographer is taking macro subjects with macro lenses and manual focusing is needed.

The shutter lever and the front control dial work well underwater with no discernible issues at all. By now the Ikelite user will have realized that there is an omission on the housing that may come to be viewed as a deal breaker for potential buyers: there is no dial on the housing to rotate the rear ring on the S100. This means that the user is not able to easily manipulate both the aperture and shutter speed to get the desired exposure, with the photographer essentially having to have one at a fixed setting and use the front control ring to adjust the other. With these constraints in mind some possible compromises are suggested:


  • For the most hassle-free compromise, set the camera to aperture priority or Av mode using the front ring to control the aperture. This allows the camera to decide the correct shutter speed given the size of the aperture you want to shoot to get the right exposure.
  • For more advanced users you can set the front control ring of the S100 to set shutter speed, choosing a fixed aperture before going underwater. Why not set the ring to control aperture instead? This is because shutter speed is a more effective way of controlling ambient light than adjusting the aperture, simply because compacts have a limited range of aperture settings due to the small sensor size. Shutter speed also has the advantage of reducing camera shake and freezing motion. For example, should the photographer want to incorporate a sunburst in the background shutter speeds of up to 1/1000s can be used whereas the maximum aperture on the S100 is only up to f8, so if your shutter speed has been set too slow it is virtually impossible to capture the sunburst effectively. If using strobes shutter speed becomes more important because the photographer will usually set a small aperture for a deeper depth of field and uses the shutter speed to control the amount of ambient light in the background.
  • There actually is a way to use the rear dial to control the aperture or shutter. This involves holding down the ring function button and choosing the settings via the macro button and the flash control button. Unfortunately all the controls are on the right side of the camera, making it extremely difficult to make changes efficiently. A convoluted two-handed position is needed to make changes via the rear dial effectively, and with practice one can make it second nature, but it may take up too much time before the photo opportunity is spurned.



Fisheye FIX S100 Housing

At the other end of the spectrum is the S100 housing from Fisheye FIX. Instead of using clear polycarbonate, this housing is constructed using corrosion-resistant aluminum alloy and can be taken to a depth of 70 meters, which accounts for its heft over Ikelite and a price tag that is almost three times as much. However, FIX sweetens the deal with a few useful add-ons bundled along with the housing, providing not one but two lens adaptors with 52mm and 67mm screw threads, and more importantly for users needing to trigger external strobes, an optical cable adaptor that can be fitted over the flash port on the housing. There is no need to fit a gear ring on the S100’s front control ring, and the camera fits into the housing smoothly and tightly, with very little chance of an improper mount. The direct video record button on the housing is colored red, which is a nice thought from Fisheye as a visual cue to users what that button is expressly used for.

The optical cable adaptor. You do get what you pay for.


There are three crucial differences between the Ikelite and FIX housings that deserve special attention: 


  • The shutter lever on the FIX, unlike the pullback trigger style of the Ikelite housing, is a vertical lever that mimics the operation of the shutter button on the S100 itself. Having a preference for either design is subjective, and if possible it is best to try out both housings to form your own impressions. The Ikelite shutter level feels more natural with regards to movement of the fingers, although I find it easier to achieve and hold the “half-shutter” position when using the FIX housing.
  • The zoom control lever has a return spring that nudges the zoom lever on the S100.
  • There is a rotary knob on the back of the FIX housing that allows you access to the rear dial. This means that the FIX housing allows you to operate the camera as you would on terra firma. Compared to the Ikelite, the FIX housing has a clear advantage in terms of ergonomics.

The shutter lever operates “naturally."


Through the paces

Remarkably the FIX housing with its aluminum-alloy construction weighs slightly less than the Ikelite housing, but it becomes negatively buoyant underwater. Complementing the housing with strobes will almost certainly require you to take off some dive weights. All the control buttons and levers can be accessed with just your right hand and the housing is a breeze to use underwater. All the buttons are easy to press and both front and rear dials move freely, making fine adjustments on the camera quick and painless. Having a return spring on the zoom lever means that the camera never hangs anymore as the zoom lever is never stuck any extreme position.

The lens mount accepted all my wet lenses smoothly, and since both the 52mm and 67mm lens mounts are screwed onto the lens port externally, it is possible to employ both of them underwater. The FIX S100 is actually more compact than the Ikelite offering, which along with its great ergonomics makes this housing a breeze to use. 

The main (and arguably only) pitfall of the FIX S100 housing is how easily the user can inadvertently depress the direct video record while diving. The direct video button is situated just below the thumb rest, which makes it easy for the thumb joint to accidentally depress it. In almost every dive I have inevitably come up a few “candid” videos mixed in with my intended footage. I thought that after some time with the housing I would have learned to avoid the button, but after eleven dives it still occurs.

Recsea Canon S100 housing

Although we didn't get a chance to review the Recsea S100, the Recsea S100 is also an excellent choice, allow full control of both aperture and shutter speed. The housing offers a large front control dial, which allows for easy use with heavy gloves, a large rear control dial, and 2 housing o-rings for added security.

The Recsea S100 housing also allows for use of an innovative quick-adapt system, which allows for easy adding and removing of wet lenses.

You can read several Recsea S100 reviews on the Bluewater Photo store website.



The Canon S100 is without a doubt a very prudent choice among compact cameras for underwater photography, especially if your main requirements are superb image quality in as diminutive a package as possible. There may be some hiccups while deploying the camera underwater but with some patience there is nothing to stop the photographer from getting amazing pictures.

Now comes the question: which underwater housing should you invest in? The Ikelite housing offers superb value, particularly for divers delving into underwater photography for the first time. Most of these new underwater photographers will probably start off with the camera in auto or aperture priority mode, so not being able to use the rear dial may not be an issue. More experienced users, who do not mind to work the buttons for full manual flexibility and some extra preparations for use with strobes, will also find the Ikelite housing a compelling choice because the quality of the construction offers exceptional value for prolonged and heavy usage. 

The FIX housing and Recsea S100 housings presents what is arguably the last word in underwater housing quality and ergonomics for the S100. The high quality controls allow one-handed operation and with the inclusion of a rear dial rotary knob the housing allows total and easy manual operation. The lofty price tag may deter some buyers, but the conveniences offered by the housing will persuade some that the premium is worth paying for. The Recsea and FIX S100 housings will be greatly appreciated by advanced users needing the full access to manual operation of the S100 and aspiring photographers who have made the decision to use the S100 for the photographic needs for the long term.

First Impressions: Nikon D800 and Ikelite housing

Michael Zeigler
UWPG editor, Michael Zeigler, got a chance to take the Nikon D800 for a few dives in the new Ikelite D800 underwater housing.

First Impressions: Nikon D800 and Ikelite Underwater Housing

By Michael Zeigler



I recently had a request for some really high resolution photos of the kelp forests at Catalina Island, and the files from my 16MP Nikon D7000 weren't quite large enough.  I needed to get my hands on the full-frame Nikon D800.  What perfect timing!

The D800 housing from Ikelite just became available at Bluewater Photo.  At 36.3MP, the D800 sensor has by far the greatest pixel count of any non medium-format dSLR currently on the market, and this was certainly the camera for the job.  Although conditions were less than ideal for what I was trying to capture, I was able to get a feel for the D800 and the Ikelite housing during my three dives at Catalina Island.

Using the D7000, Ikelite and Sea & Sea Housings

Although I have been shooting the Nikon D7000 in the Sea&Sea housing for the past six months, I'm no stranger to Ikelite dSLR housings as I owned one with my Nikon D90.  It was my first go, however, with a full-frame camera.  Here are my first impressions of the D800 and the Ikelite underwater housing.

I managed to get my hands on the camera and the housing the evening before the trip, so I had limited time to get to "know" the camera.  I was, however, able to at least set the menus similarly to my D7000.  All the photos below were captured using a Nikon D800, Sigma 15mm fisheye lens, Ikelite housing with 8" dome port, and dual Ikelite strobes.



Close-focus wide-angle shot of a giant-spined sea star at Catalina Island, California. This sea star was just 2 inches from the dome port.  F10, 1/160, ISO 400.


Nikon D800 - Key observations


Having shot the D7000 for several months now, I was surprised at how even more solid the D800 felt in my hands.  I definitely noticed the weight difference too (900g vs. 780g).  The controls were easy to use, and I especially liked the larger multi-selector pad.  The only control I couldn't get used to was the ISO button being located on the top left side of the camera.  Overall I enjoyed using the D800 for the short time I had it. 

Depth of Field

  • The depth of field is a lot more shallow with a full-frame camera compared to that of a cropped sensor (e.g. the D7000).  The above photo shows the fish in the background are out of focus, even though I'm shooting at F10 with a 15mm fisheye lens (the wider the lens, the deeper the depth of field).  The difference in focus would have been much less dramatic on the D7000 at 10mm with my Tokina 10-17mm fisheye. 10mm on the Tokina with a 1.5x cropped sensor is the equivalent of 15mm on a full-frame sensor.

Big Files

  • Get a fast SD or CF card.  The RAW, uncompressed files are 75MB each (7360 x 4912 pixels).  The card I had for the rented camera wasn't fast enough, and I had to wait a few seconds for the images to appear for review.  You can, obviously, choose to compress the RAW files in the settings, or shoot JPEG.

Other key differences underwater

  • Video is easy to shoot with the D800 via the Live View button, and a dedicated red "record" button near the shutter release.

  • The field of view through the view finder on the D800 is 100%.  No surprises in the corners of your final photograph!

  • The multi-selector pad on the back of the camera allows for diagonal movement of the focus selector, and allows for diagonal movement of the image review.  That makes it really easy to check the corners of the image for sharpness, etc.  This function is not available with the Ikelite housing, but it will be with the Nauticam D800 underwater housing.

  • The light meter was visible in the top LCD screen.  I could see this being nice while using a tripod in a low position.  After framing the shot you wouldn't need to kneel down to adjust the settings using the light meter in the view finder.

  • I found that it focused just as fast as my D7000.


Here are some important D800 specifications

  • 36 megapixel, full-frame sensor
  • Offers 15.4 megapixels at a 1.5x crop (you can use your Tokina 10-17mm!)
  • Offers 1080p high def video at 30/24fps, 720p at 60/30fps
  • ISO range 100-6400
  • Takes CF & SD cards
  • Speed limited to 4fps
  • Auto-focuses at F8 like the Nikon D4 does, great for teleconverters!
  • 51 auto focus points, price tag of $2,999
  • Very hard to get right now! There is a long wait



It took a few minutes of slow approach along the bottom to get this close (one foot) from this bat ray.  F11, 1/250, ISO 400.   Publisher's note - as someone who has shot this scene many times with a D300 & D7000, I'm quite impressed by the detail in the photo, and the range of the blue color in the background! 


Ikelite Underwater Housing for the D800

The clear, heavy-duty polycarbonate construction of the Ikelite housing made seeing the controls easy, and also allowed me to view the LCD screen on the top of the camera right through the housing.  The electrical bulkhead and TTL circuitry allows for fine-tuning of strobe power via easy-to-control knob on the back of the housing.  Although the housing is larger than most aluminum housings, I found it easy to control underwater.  Just be sure that all the controls and knobs are pulled "out" when putting the camera into the housing, to ensure proper alignment of the controls once the camera is secured in the housing.  Once secured, always be sure to fire at least one test shot (true for ALL housings) to make sure the controls are positioned correctly, the bulkhead connector is hooked up, and to make sure you didn't leave the lens cap on.  Also take a test shot with your strobes on.

  • The housing, 8" glass dome, and two Ikelite strobes were almost perfectly neutrally buoyant with just a few strobe arm floats.

  • I really liked the dedicated AF-ON button on the camera, which I primarily use for focusing when the camera is in a housing. However, this was only available via a button the back of the Ikelite housing.  I was able to program the AE-L/AF-L button for the AF-ON functionality, which was accessible via a lever that I could easily reach with my right thumb while shooting.

  • The top LCD screen was clearly viewable through the housing, which was nice.  I never had to access the "info" button to see the settings on the back of the camera.  As I mentioned above, the light meter was also visible in the top LCD screen.  I found this to be a nice feature while I was cruising through the various light conditions of the kelp forests.  I could easily look down and adjust the settings for the changing ambient light conditions.  This way I could be ready for "the shot," should something interesting decide to visit.

  • I found it a bit cumbersome to switch back and forth between AF and M modes, using the switch on the lower left side of the housing.  Due to the way the camera slides into the housing, the switch is a one-way switch.  In other words, in order to switch back to AF from M, for example, I needed to physically pull the control knob out, look through the housing to see where the mechanism was located, then align it was the other side of the switch.  Once aligned, I could twist the knob and engage the switch to make the change.

  • The ISO of this camera is located on the top left side of the camera body.  This is accessed with the Ikelite housing via button.  I highly suggest that you turn on the "Release button to use dial" setting in the Custom Settings menu of the D800.  This will allow you to press the button, release the button, and adjust the setting using the main dial without having to use both hands at the same time.  My D90 did not have this feature, and it's a great to have with the Ikelite housing.

  • The only control that I did not have access to was the metering mode (i.e. matrix, center-weighted, spot).  It is operated via a small dial, located around the perimeter of the AE-L/AF-L button.  I usually leave my metering mode on center-weighted anyway, but it would be nice to access this, just in case.  Just be sure it's on the setting you want before you close the housing!

Final thoughts - Nikon D800 underwater

I really enjoyed getting the opportunity to use the D800 above and below the water.  For use topside, the camera had some "nice to have" features that included switch to close the view finder when using a tripod, a dedicated AF-ON button, and a separate button to raise the flash (separate from the button usually used to change the flash settings). 

For use underwater, I still prefer my D7000.  The increased depth of field comes in handy for me, especially when shooting macro or supermacro.  Plus, I love the versitility of the Tokina 10-17mm fisheye, which is not compatible with full-frame cameras.  Personally, I will not consider switching to a full-frame camera unless I find it absolutely necessary to produce massive prints of my work.

All in all, it's a fantastic camera, and worth the investment if you use the camera to its fullest potential.  The Ikelite housing is solid, and a great option if funds play a part in the decision making process.  I am looking forward to getting my hands on the Nauticam D800 and Sea & Sea D800 housings as well.

First Impressions: Panasonic GX1 Mirrorless Camera

Kelli Dickinson
Review of Panasonic's new mirrorless camera, the GX1, and its performance underwater.

GX1 First Impressions

Panasonic GX1 Mirrorless Camera

Nauticam GX1 housing

By Kelli Dickinson









Panasonic has a new mirrorless camera on the market, the GX1. This camera takes things up a notch from the popular G series cameras that were previously released, the GF1, 2 and 3. Relabeling the camera as GX as opposed to GF is possibly meant to make it clear to consumers that Panasonic has a whole new vision for this model. The GX1 offers a 16MP "live-mos" sensor, 3" LCD screen and ISO sensitivity up to 12,800, in addition to improved auto focus and touch screen capabilities.


GX1 Design & custom settings

Overall I was very pleased with the design of the GX1. It fits well in your hands with a grip that is not too large but also not so small as to render it useless. The buttons on the back are arranged in a classic and easy-to-use manner. There is a mode dial on the top of the camera for quick and easy mode selection. The mode dial includes your standard M, A, S, P, Scene and Art Modes, but also has two Custom settings where you can store a favorite camera setting for quick access. 


Panasonic's GX1 offers an easy-use mode dial which includes two custom settings, switch on and off and a separate record button for quick video access


The GX1 appears to take a step back to more classic design than going with what is trendy with newer cameras who all strive to be the smallest and sleekest with wheels and touch functions rather than standard buttons and dials. The GX1 maintains a nice balance between classic styling and new technologies with an easy-use control dial on the back, a more standard array of buttons as well as touch screen capabilities.

The blocky body design allows room for the standard array of buttons, which is refreshing in an age where sleek design often takes precedence over the quicker function of buttons. A circular array of four buttons with a center main menu button offer quick access to ISO, white balance, single/continuous/timer and auto focus mode settings, while four buttons surround those central ones offer display settings, auto/manual focus selection, a quick menu and a customizable function button. In addition there are two buttons above the LCD, play for picture review and an AF/AE-lock which is also customizable. 


The GX1 takes a stand with a more classic design keeping important buttons and dials as well as including new features like touch screen capabilities.


As a primarily Olympus camera user, I found the aperture/shutter speed control dial on the GX1 to be fantastic. Similar to dials found in dSLR cameras, it made it very simple to change modes and literally dial in your settings quickly. Unlike the Olympus PEN series mirrorless cameras, which use the up and down and left and right buttons to control shutter speed and aperture respectively, the simple turn of a dial is made for quick and easy setting changes. Be careful though: since there is only one dial for controlling both shutter speed and aperture, you need to press the dial in to switch between the two functions. Move too quickly while changing settings and you may find yourself suddenly changing the shutter speed when you meant to be adjusting aperture. This was also fairly problematic when the camera was in an underwater housing.

One downside to the camera I found was the menu system. The menu takes some getting used to, as the function, or "quick menu," which is usually found in the center of the main buttons on many camera brands, is actually now located as the bottom left button, and the main menu is accessed through that center button. I found this confusing, as my Olympus and many previous compact cameras had trained me for the opposite.

The large 3" LCD screen is clear and bright, making it easy to review and set up shots, even while underwater. The GX1 includes a useful orientation sensor that allows you to easily orient the camera for horizontal, vertical and any diagonal compositions. This is turned on and off through the display button. 


GX1 Focus speed & performance

Overall I was impressed with the performance of this camera. The auto focus is extremely fast, making my old Olympus EPL1 feel like a dinosaur. Even underwater, the GX1 would focus just about instantaneously, I even had one moment when a small rockfish darted at me from a black crevasse, and the camera was able to focus and snap a shot as it turned and darted off. Definitely impressive. Paired against the newer Olympus models the auto focus is equivalent, if not even a bit faster.  


Not the most stunning shot, but this kelp rockfish surprised me as it darted out of a crevasse and I quickly snapped the shutter - thanks to the fast focus speed I was able to capture him as he darted away.


I was able to test the camera with the standard 14-42mm Lumix Vario lens. Overall the lens worked well, with nice optics providing good clear pictures, however focus distance is definitely a limiting factor with this lens. I found the closest focus distance available offered images up to 4 inches across, unlike my Olympus EPL1 14-42mm lens which allows focusing for images up to just two inches across.



Panasonic 14-42mm PZ lens

Panasonic has also released this camera with their new 14-42 Lumix Vario PZ (Power Zoom) lens. We tested this lens in the store, and it seems very well suited to video, with the power zoom design, and the ability to control how quickly the lens zooms. The lens zooms silently, which is another nice feature. The macro capability is a little bit better than the regular version of the lens.

The plus side to focus limits on the two kit lens options is that Panasonic makes a really nice 45mm macro lens and Olympus is releasing a new 60mm macro lens for the micro four thirds cameras sometime this fall. If you really want great macro, there is no substitute for a dedicated macro lens, and both of these will work well with the GX1. 

I really enjoyed using this camera, and it shows a lot of promise for great underwater use. The easy, functional design, quick auto focus, 16MP sensor and other neat features such as the orientation sensor will all aid in allowing for easy composition, control and capture of great underwater photos. 

Nauticam GX1 Housing

Nauticam GX1 housing

The Nauticam GX1 housing is very small and well built. It felt designed to fit in your hand very well. The shutter button is sensitive and easy to get to, and half-press focus is easy to achieve. Ports are available for all lenses you would want to use, including the 8mm fisheye, 7-14mm, 9-18mm, both Panasonic 14-42mm lenses, and the 45mm macro lens. The 14-42mm PZ lens zoom gear has not been released by Nauticam yet, but hopefully it will soon.

The port release system worked very well, no twisting of the port was necessary and changing ports could be done quickly. All buttons were easy to press while holding the housing, and the knob for changing aperture / shutter speed was easy to use even with 5mm gloves on. One dial changes both aperture and shutter speed. To switch from one to the other, you simply press the dial. The only downside of this design is if you change your aperture or shutter speed too quickly, you may find that it switches from one to the other inadvertently. 

Priced at $1,200 - we find that this is the best deal on the market for an aluminum housing for a mirrorless camera. Competing with the GX1 is the Olympus OM-D E-M5 in a Nauticam housing. The camera and housing costs more, but it is a slightly higher end camera that we will be reviewing very soon.

GX1 Camera and Housing feedback from Swee Sin Eng

Swee used the camera and Nauticam GX1 housing on a recent trip to Komodo, Indonesia. Here is some of his feedback:

Using the GX1 and 45mm macro lens:

Surprisingly the 45mm macro lens was quite responsive and accurate. I had no problem using it in day time, and it auto-focused great. For night dives, i used it with Sola 600 light and it work perfectly. The only problem, was when the red focus light was on, the screen become completely red and it was hard to see the subject. The macro lens can take a photo 18mm across at 1:1 magnification, which is really nice!

The macro port does come with a 67mm thread, but using a wet diopter with this lens means the focus distance is very, very close to the port. I did put a wet lens on the port, and the camera did hunt a lot when trying to focus.

Using the Panasonic 8mm fisheye lens

The Panasonic 8mm fisheye is a very sharp and wide lens, and allows you to create dramatic photos. However, it show vignetting in the normal 4:3 mode. I had to switch it to 16:9 mode to get rid of the shadow causing by the dome shade. The flash sync speed is locked at 1/160th, similar to other mirrorless cameras, which means it is quite difficult to shoot a sunburst shot.

First Impressions: Using The Olympus E-PM1 Underwater

First Impressions: Using The Olympus E-PM1 Underwater

By Kelli Dickinson


I recently got the opportunity to take the new Olympus Pen "Mini" camera, the E-PM1, out for a couple of test dives. The Pen "Mini" is a slimmed-down version of the previous model in the line, the E-PL3. I own and have been shooting with the E-PL1, which was the first Pen series camera to have an underwater housing, and I absolutely love it. To avoid confusion, I will just refer to the E-PM1 as the "Mini" from here on out.  



Right off the bat I noticed several differences between the standard Pen series cameras and the Mini. Namely, the camera has been slimmed down, with Olympus doing away with the mode dial on the top of the camera, some of the buttons on the back and the internal "pop-up" flash. The flash is now a snap-on accessory to the hot-shoe for both the Mini and the E-PL3. The Mini is menu-driven for changing modes and several other functions. While this could seem like a negative at first, I found that it was not an issue. The menu is organized well - with one push of a button all the modes show up on the screen and you just have to scroll over to the desired mode. I found it easy to change modes underwater when I needed to. All other functions, such as adjusting shutter, aperture and white balance are done in the same way as all the other Olympus Pen series cameras.

The housing for the Mini has the same design, build quality and size as the housings for the other Pen series cameras. Olympus' durable polycarbonate housing has not changed its design throughout the different camera models, with the exception of adding a focus light option in the E-PL3 and Mini housings. The focus lights are not overly bright, and in my opinion you are better off going for the housing without lights. This housing will accept the dome port for the 8mm fisheye, after an easy customization, and costs less. Just like the previous housings, the housing for the Mini has tiered buttons, making it easy to use even while wearing thick gloves. All of the buttons are labeled, which I have always loved, making it easy to remember which button does what.

I took a customized housing out on a dive trip to Anacapa Island with the Panasonic 8mm fisheye lens and Precision Dome Port with a Sea & Sea YS-110a strobe.

In the housing the Mini functions just like the other Pen series cameras, changing your aperture or shutter speed, adjusting the flash mode or white balance are easy and are done exactly the same way. Like the previous models, aperture and shutter are controlled by the four buttons on the back of the camera, and ISO and white balance are contolled through the function menu, activated by the "OK" button in the middle of the button clusters. All of these features are accessible inside the Olympus housing. Other than the housing missing a couple of buttons, you would be hard pressed to tell the difference in operation between the Mini and any other Pen series camera.*

This little camera functions wonderfully. The focus is much faster than my old EPL-1, and equivalent to the more expensive E-PL3. I fell in love with the Panasonic 8mm fisheye lens immediately. The 180* field of view is fantastic, except for those times when you happen to capture the edge of your strobe in the photograph. The lens is clear and bright, and paired with the larger micro 4/3rd's sensor this set-up offers great quality that is very affordable for wide-angle shooting.

Battery life on the Pen Mini is excellent, it easily lasted three long dives in the chilly California waters without an issue. All in all I was very happy with this new simplified Pen camera. It works as well as the other Pen models, for less money and without all the extras getting in the way.

*The only downside I encountered is that the loss of a few buttons meant that there is no way to review all of your pictures while in the housing. The camera relies on the scroll wheel to move back through your images, and there is no access to that wheel through the housing. You can still easily review the last image shot, as well as zoom in on that image to check focus.
