Nauticam Housing for Panasonic GH4

Nauticam Announces Housing Support for the GH4 in Two Ways...

By Brent Durand, July 9, 2014

Nauticam has announced a new housing and a housing upgrade kit to provide two ways for users of the Panasonic LUMIX DMC-GH4 to get their camera underwater. The new housing is designed specifically for the LUMIX DMC-GH4 while the upgrade kit allows owners of the NA-GH3 housing to pay just $20 to allow full functionality of the GH-4 in the older housing.

The new housing is what you'd expect from Nauticam: small, lightweight, ergonomic and supported by a wide range of ports and accessories to capture 4k video and 16MP stills. The press release and photos below provide all the details.

Housing for Panasonic GH4

Innovation Underwater

The Panasonic LUMIX DMC-GH4

Ultra HD. 4K. Whatever you call it, it is here now, as digital cinema enabled movie theaters and 4K TV's are beginning to take over. The new GH4 shoots 4K video, at up to 30fps, recording it to fast SD cards (UHS Speed Class 3 [U3] recommended). 

The news about 4K is so exciting that it is easy to forget about the rest of the features of this camera. The GH4 is a micro four thirds (m4/3) mirrorless camera, with a 16 megapixel CMOS sensor, capable of a still photography burst mode of 12 fps. The contrast detection autofocus is fast and accurate with 49 focus points, and an easy to use focus mode lever/button that makes changing from autofocus to manual quick and easy. The combination allows for "thumb focus" with the AF-ON button whether the camera is in one of the autofocus modes or in manual focus mode. Image quality is excellent, and is a step up from the already very good GH3. 

With as much buzz as the GH4 gets about video, it's easy to forget this is a terrific stills camera too.

The large, bright 3" 1Mdot OLED panel is fully articulated, and the camera sports a high resolution 2.4 Mdot electronic viewfinder with eye sensor or dedicated button to switch between the two views. The camera also supports external monitors and recorders. There is an option for a "clean" HDMI output for recording, which supports both the HD and 4K modes via the HDMI 1.4 specification.

For video, the GH4 supports no less than 23 different resolution/frame rate combinations, spanning NTSC, PAL and Cinema frequencies, up to 60 fps, plus a special "Variable Frame Rate" (VFR) mode that enables the shooter to record at a different frame rate than is specified for playback. This makes in-camera slow motion (up to 400% speed reduction) and in-camera time lapse (up to 1500% speed increase) possible. 

Nauticam NA-GH4

Nauticam’s tagline is "Innovation Underwater", and the company is dedicated to continuing innovation in this industry, while helping to protect customer investments in existing Nauticam gear whenever possible. Case in point, Nauticam offers a user installable upgrade kit (p/n# 17753) to enable the existing NA-GH3 housing to enable the GH4 to work in that housing with full functionality. In addition, the new NA-GH4 housing can be used with either the GH3 or GH4 camera. 

Relentless innovation demands that a new housing be designed for the GH4 and is able to incorporate new features that have debuted on more recent Nauticam housings, not to mention a couple of new features that are first seen in the new NA-GH4. One first is the unique placement of the ISO control. ISO is key for video exposure (think "gain" if you come from the video or cinema worlds), and this new control makes changing ISO very quick and easy, essentially re-routing this control back to the right thumb. The button is just in the right place, ideal for quick access but not easily bumped accidentally. 

Another key concern for video - white balance - is achieved with another control that is re-routed for maximum ease of use. A push lever, accessible by the right thumb with no reach, engages the white balance button. From there, any of the white balance settings can be accessed, including any of the four custom white balance banks. To perform a custom white balance, the shooter would press the up arrow, point the camera to the white balance target, and press the OK button, all easily accomplished with an absolute minimum of reach.

Nauticam has always featured the only over-molded rubberized handles in the industry... the NA-GH4 now not only includes the handles, but they are angled forward at just the right angle for shooting steady video. The handle placements are adjustable horizontally, and include a stabilizing bracket that steadies the rig with heavy lighting attached. 

The two command dials (Aperture and Shutter Speed) are at the fingertips, and can be reversed to put aperture on the forward dial if that is the shooters preference. The GH4 features 5 programmable custom functions, and they are all placed for easy reach. The combination lever and button of the GH4's AFS/AFC/Manual + AF/AE Lock is separated to two separate controls, making the AF On function available for "Thumb Focus." The GH4 allows autofocus via this button even with the lever set to Manual Focus, meaning switching between thumb focus and half press focus style can be done instantly. The Video Record button is engaged via a button placed at the right thumb, and easily is distinguished from other pushbutton functions.

One of the programmable functions (typically Fn5) is used to switch between the EVF and OLED panels. For shooters who decide they do not need to switch, Fn5 could be re-programmed for other functions, such as Photo Style, Video Recording Quality, VFR, Peaking, or any of dozens of other functions. 

The housing gains a new-style port locking mechanism, which will be familiar to people who have seen Nauticam SLR housings. This locking lever made it’s mirrorless debut with the Nauticam NA-EM1 housing, and is an iconic symbol of Nauticam innovation. The new locking lever makes port changes effortless, quick, and just as secure. 

Tripod users will find 3 1/4-20 tripod holes, with extra space allotted for the width of standard tripod plates, meaning the housing can easily be opened with tripod plate attached. 

The NA-GH4 comes standard with the Nauticam vacuum system electronics built in. By default, this serves as a audible and visual leak detector, but add a Nauticam M14 Vacuum Valve, (p/n# 25611) and it becomes a vacuum check system - confirming watertight integrity before, during and after the dive - which means peace of mind. 

Milled from solid aluminum, the housing is rated to 100m/330ft depth, and is rugged and ready for use!

Lenses and Ports

One of the strengths of the Micro Four Thirds system is the wide selection of excellent lenses from both Panasonic and Olympus, supporters of m4/3. GH4 ships body only, allowing the shooter choice. The Panasonic Panasonic Lumix G X Vario 12-35mm f/2.8 is an ideal "walk-around" lens for this camera, with a focal length range that suits many shots. Or for video shooters, the Panasonic Lumix G X Vario PZ 14-42mm covers a similar focal length but adds the power zoom functionality. These lens are also useful underwater as a fish portrait type of lens, or a shy shark lens. 

For those wanting to further expand their range underwater, lenses like the Panasonic Lumix G Fisheye 8mm/F3.5, Olympus 9-18mm, Panasonic Lumix G Vario 7-14mm f/4.0, Panasonic Leica DG Macro-Elmarit 45mm f/2.8, and the Olympus M.ZUIKO DIGITAL ED 60mm f/2.8 Macro are all supported. These are really the "workhorse" lenses for m4/3 underwater, and would be highly recommended. Panasonic and Olympus also offer a number of "pancake" type fast prime lenses that are of excellent quality and minimal size. Lenses in this class to consider would include the Panasonic Lumix G 14mm f/2.5 and Olympus M.ZUIKO DIGITAL ED 12mm f/2.0.

One of the most versatile lenses available for any system is the Olympus M.ZUIKO DIGITAL ED 12-50mm F3.5-6.3 EZ Lens, which is a power zoom that features a built in macro mode.  Nauticam is the only housing manufacturer that fully support this multi-purpose lens, and it is worth considering for someone interested in shooting macro and fish portraits on the same dive. Add Nauticam’s pioneering SMC, the first accessory optic designed exclusively for in water use, for even higher magnification on the macro side.

The Nauticam Super Macro converter is an ideal add on for macro enthusiasts, providing reproduction much greater than life size with minimal distortion and aberration, and works well with the Olympus 60mm macro lens. 

Generally, autofocus is used underwater with wide angle zoom lenses. For cases where manual focus is required, however, Nauticam provides a solution for the Panasonic 7-14mm and 12-35mm lenses. The 6" Wide Angle port with Focus Knob (#36164) along with #36043 P714-F focus gear (for 7-14mm lens) and #36042 P1235-F focus gear (for 12-35mm lens) provide this functionality. 

Nauticam supports more lenses for m4/3, and has more m4/3 lens experience than any other underwater housing manufacturer. 

Magnifying Optical Viewfinders

Nauticam produces a “straight” 180º magnifying viewfinder (#32201) and a 45º angled viewfinder (#32202) that provide a bright, corner to corner view of the GH4’s excellent EVF. A patented external dioptric adjustment allows personal adjustment to a sharp-as-a-tack standard underwater and viewfinder changes can be executed in less than 30 seconds without using tools. Exceptional composition and focus accuracy have never been more accessible. An optional LCD window (p/n # 17751), containing the viewfinder mounting ring, is required to attach these finders. For owners of NA-GH3, this is the same window used for that housing.
