Nauticam Opens the Underwater World to the GH2 Shooter
Rated to a depth of 100m, the new NA-GH2 is a rugged aluminum housing that continues the Nauticam tradition of ergononomic controls and innovative thinking

The NA-GH2 housing inherits numerous innovations from earlier Nauticam housings like the easy-to-use-yet-secure locking latch from the NA-NEX5 housing, ergonomically placed buttons and the patented Nauticam port locking system. As with all Nauticam housings, innovative ergonomic access to key camera controls comes standard.

The camera slides easily into the housing with no need to preset any controls, and the housing is securely closed with a locking rotary latch.

This housing puts all of the important controls on the camera within easy reach, and even makes some of the controls on the housing easier to manipulate than on the camera itself. Case in point, the GH2 command dial can be both turn and clicked. While this may be easy to do on land, underwater it could prove difficult, and housing manufacturer have previously struggled with this sort of control. The Nauticam engineers very cleverly separated the dial function into two separate controls on the housing, making use of both functions a breeze.

A Multitude of Controls
From the sculpted shutter release to the knurled zoom knob, this housing features all of the controls an underwater photographer needs to drive the GH2. A flash popup button is provided for fiber optic strobe control, along with a flash inhibitor that is useful when flash is not wanted, such as during silhouette shooting.

Access to the GH2 mode dial, on/off switch, drive mode, AFS/AFC and focus area controls are done with dials on the top of the housing. The 3 programmable function button are all made available on the housing, including Fn1 on the top of the camera via a rocker key. Fn1 will be a particularly useful key, allowing one easy access to things like flash exposure compenation.

Switching between LCD and EVF viewing is easy with the provided LCD/EVF button. A lens release button allowing lens changes while a zoom gear is attached without opening the housing back is standard equipment. An audible/visual moisture detector which places the visual indicator at the level of the eye is standard on the NA-GH2.

Adding to the Nauticam Port System
The port system for GH2 expands upon the existing port system for the NEX-5 housing, adding additional ports for the superb Panasonic Lumix m4/3 lenses. Olympus m4/3 lenses and Leica m4/3 lenses can be used with this camera as well, further expanding the lens choices. Lenses initially supported include the Lumix 14-42mm, the Lumix 14mm/2.5, the Lumix 8mm Fisheye, the superb Lumix 7-14mm, the Leica 45mm macro, Olympus 14-42mm, and Olympus 9-18mm. Zoom gears are available for the zoom lenses listed here.

Panasonic Lumix DMC-GH2
GH2 is loaded with features that make it appealling to the underwater photographer. It has the basics covered, with fast RAW capture, manual exposure mode, and TTL in most modes including manual exposure mode. Add to that a 16 megapixel effective (18 megapixel total) high quality multi-aspect ratio sensor, 1080i/p 60fps video, excellent high ISO performance, fast autofocus, and a huge number of customizable options, and you have a superb underwater imaging machine. Autofocus on some m4/3 cameras is less than desirable, but not GH2. Thanks to the high scan rate sensor, the contrast detection autofocus on GH2 is not only very fast and accurate, but allows for autofocus during video shooting. GH2 offers considerable control over how autofocus operates (AFS, AFC, and Manual, Focus Areas, Pre Focus, Focus Priority, and provides an AE/AF Lock button, programmable back focus, and more).
