Olympus Tough TG-4 Camera Review

A review of the TG-4 and housing for underwater photo and video, including new RAW recording and Microscope Mode
By Brent Durand

The Olympus Tough TG-4 compact camera sits in a class by itself. The 16MP camera is waterproof, shockproof, crushproof, freezeproof and dustproof.... oh, and it even has a dive housing for serious underwater photography. This combination makes the Olympus TG-4 a great camera for those who put their cameras through demanding topside and underwater use but don't want the bulk and expense of larger systems. Highlights include microscope mode, which lets you shoot scary-close to your tiny subject, and RAW image recording for complete post-processing control.

Update: The Olympus Tough TG-5 and Olympus Tough TG-6 greatly improve on the image quality and many other specs that we loved on the TG-4. They are top of the line compact underwater cameras, and we highly recommend checking them out as well in our Olympus TG-5 underwater review and Olympus TG-6 underwater review

Olympus TG-4 Underwater Housing

The Olympus TG-4 underwater housing (PT-056) can be purchased with is sold separately from the TG-4 camera, and we highly recommend it for anyone planning to take the TG-4 scuba diving. The housing is small, lightweight and a great value. And although the TG-4 is technically waterproof to 50ft, the housing will allow divers to use strobes, more wet lenses for wide-angle and macro, handles and other accessories in shallow water or much deeper depths.

  • Filter Thread Size:  52mm

  • Weight:  Approx 1 lb (430 g)

  • Includes:  O-ring, silica gel, silicone grease, LCD hood, lens cap optical cable adapter, anti-reflective ring

Thoughts from the Lab

In reviewing the specs of the new TG-4 compact camera, we think it will be a nice camera for those who want a compact, versatile camera that takes high-quality images. Take the camera on your dive trip and bring it in the pool, in the river on your hike, toss it in your daypack and then put it in the Olympus housing with a strobe or a video light before your scuba dives. This is some great versatility.

The Olympus TG-4 is also much more desireable now that it shoots 16 MP RAW images. Recording images in RAW format saves more data, allowing for custom post-processing in your computer photo software.

Underwater shooters will be very interested in the new Microscope Mode. How close is the minimum focus distance?  I don’t know – the camera focuses on the lens cap… can’t get closer than that!

The TG-4's WiFi ability also makes it easy to send your images to a tablet or mobile phone (via the Olympus Share app) for editing and posting to your social networks - no need to lug a heavy computer around with you. There is also built-in GPS for keeping track of your adventure.

Simple camera controls make the TG-4 easy to use. You can record video with a press of the red button on back of the camera, which is indented so that it doesn’t start recording unintentionally. All other controls are positioned for easy access with your right thumb.

The housing is actually the same as the TG-3 housing, which is great for those who would like to upgrade for RAW and Microscope Mode. Housing controls are clearly labeled and easy to press. Replace the pop-up flash diffuser with a flash mask when using a strobe(s). One of the best housing features is the cold shoe mount on top, which allows you to mount a video and/or focus light on top of the housing, which is a great solution for bringing light to your photos without investing in a tray/handles and strobe(s).

Thoughts from the Water

I tested the OlympusTG-4 on one exciting scuba dive and one snorkel, using the camera without the housing (the dives were shallow). These are the underwater photos and video you see in this review, with details included in each caption.

The TG-4 was really fun to use. Normally I shoot with at least one strobe, but the TG-4 produced some great photos using only a video light. I handheld the light, however the light could also be mounted to the housing cold shoe, creating a very compact system – it’s really all you need.

Underwater, the TG-4 was very intuitive to use. I shot in Aperture Priority mode, allowing you to shoot f/2, f/2.8 or f/8. For those without a firm grasp of aperture, you can shoot in P mode, which is full automatic.

While the camera isn’t fully manual (good for entry-level photographers), it does allow more experienced users to get the shot. Reviewing images was easy when working on precise lighting, and when I wanted to shoot quick action while swimming, I turned off the preview (after each shot), enabling me to shoot a rapid sequence.  (note that I shot each frame – there are also high-speed shooting modes that capture many frames per second, but this delivers jpg files, not RAW).

The Olympus TG-4 housing allows use of wide-angle and macro wet lenses, but there is also a fisheye (wide-angle converter) wet lens for the camera itself, which I used to capture the split shots in this review.

Switching from photo to video is super easy: push the shutter to shoot photos, and push the red record button for video. This is great for those who enjoy shooting photos and videos.
