Aquatica AGH4 Preview: 4K cinema for the consumers!
Buckle up, the future is here. Panasonic GH4 brings cinematic 4k video performance to your door step, with its Micro 4/3 lens mount, this camera benefits from a very large selection of lenses. In fact, an astounding array of lenses from Panasonic, Leica and Olympus, just to name a few, are offered in this lens mount. Add the fact that is has 4x times the resolution of HD, one can easily understand why the GH4 will stand out head and shoulder above its competitors. Video shot on Ultra HD 4K is razor sharp and needs to be experienced firsthand to be believed!
Recording video in Ultra HD at resolution of 3840 x 2160 in 30p/24p or 4096 x 2160 in 24p, compared to standard HD which is 1920 x 1080p, the 4k quadruples the standard HD resolution. It is also the only one in its league to record 4K 30p directly to a SD card, this is big news, since there will be no need for a bulky external drive!
If current post production and viewing technology has not yet caught up with the 4K, you need not worry, even scaled down to a 1080p, the footage still looks noticeably sharper, the added resolution offer a generous margin in post processing cropping and stabilization. The GH4 offer some nifty features in 1080P as well, silky smooth slow motion, less compression and wider latitudes for post processing and editing.
Files sizes are surprisingly small, being similar to what pro DSLR will offer in 1080P, managing your footage is and will definitely be easier to manage, obliviously, in order to extract the maximum out of the GH4, only the best and fastest memory card, such as SDXC-UHS-II should be used, slower cards will do fine for still images and lower resolution footages.
The Panasonic GH4 would be an impressive camera, even if meant for shooting stills only! It sure shine in this department with its 16mp sensor, very desirable flash sync speed of 1/250, increased ISO/dynamic range and burst rate of up to 12 frames a seconds even in RAW!
About The Aquatica AGH4
Aquatica fully understands the requirements involved for shooting high quality video, with the acquisition of Amphibico, the legendary video housing manufacturer, came a wealth of expertise in the field of video capture, it is this knowledge, coupled with over 30 years of manufacturing housings ourselves, that is now distilled into this AGH4 housing. By natural necessity, a housing needs a sound, practical and ergonomic design for video, fiddling around to access controls can easily ruin your important sequence. You need intuitive and precise access these controls, so you can keep your eyes on the monitor and, importantly, the housing needs to be a well balance and stable setup, the Aquatica AGH4 delivers on all aspects.
On previous camera models, some form of video mode was offered, while it was genuinely considered an interesting feature to be had, it definitely lacked the awesome performance that the Panasonic DMC-GH4 now brings forth. This level of excellence in video needed to be taken into account in our housing design.
This view of the right hand side clearly demonstrate that, while being a compact housing, the controls do remain accessible, even when wearing thick cold water gloves. The shutter release, video record lever, aperture and shutter knobs, programmable AE/AF LOCK lever are all reachable with your right hand resting on the grip.
ISO is a key control for video exposure, and our engineering team has put its access lever exactly at the right location, essentially putting it under your right thumb, this lever being at right place means you have quick access to this control, without removing your hand from the grip.
On the left side, right above and forward of this non obstructive latch, one will find the zoom/focus control knob, it’s position allows it to be rotated with the tips of your fingers, it is setup with a silky smooth gearing ratio that will ensure a smooth transition when zooming or manually focusing a lens.
Comprehensive Port System
The AGH4 housing uses the already established 4/3 Micro series of ports and accessories; Aquatica is renowned for the quality of its optics and this is no exception to the rule, every lens supported by Aquatica is evaluated on an optical bench, and from the data gathered, we can determine the best port to use and, if required, the extension ring length that will match the optical center of the dome to that of the lens. This all important step is necessary if one wants to extract the maximum optical performance possible from a lens and port combination.
The system is further expanded with the addition of the upcoming 4/3 Micro series to DSLR port adapter. In essence, a step up adapter that will allow our regular DSLR ports to be mounted on the Aquatica 4/3 Micro series housings. Thus offering the Aquatica AGH4 the largest and finest selection of underwater ports in the industry. This port adapter also help integrate the 4/3 Micro series housing to existing DSLR system by sharing the existing ports.
Fully aware that real life is not a controlled environment, we recently introduced the SURVEYOR moisture and vacuum sensor alarm, which comes as standard equipment on the AGH4 housing. The moisture detection feature remain on constant duty to inform you, by way of audible an visual signals, of any possible water entry, no matter how minute this one would be.
The SURVEYOR circuit integrates a vacuum sensor, if one wish to take full advantage of this vacuum pressure option, then the simple addition of the accessory vacuum pump and pressure valve (19228) to the housing is all that is needed. This option is also available as a preinstalled kit, which would tested at the factory by our own technicians prior to shipping or it can be purchased later and installed easily by the user.
The Amphibico Latch
This straightforward push, rotate and locking latch has been used on over 10,000 Amphibico and Aquatica housing for decades now, it is simply the best in the industry.
The Aquatica Hand Grips
Handling the housing is done via a pair of the most comfortable hand grips in the industry, they are sturdy yet very lightweight, and offer mounting points that will handle the lighting system of your choice without the need for obstructive reinforcement brackets or supports. These grips are removable in less than a minutes with the supplied hexagonal wrench, making the storage footprint space minimal.
Like all current Aquatica housing currently made, the shell is milled from a solid block of 6061 T6 aeronautical grade aluminum, black anodized to a military specification and then, for further protection, a resistant polyester electrostatic powder coating is applied and baked on. This process ensures that your investment will last you a life time.
Push buttons pins and control shafts are machined out of the finest grade of stainless steel, every component used in an Aquatica housing undergoes a series of stringent quality controls insuring that they respect our strict tolerance.
