Nauticam NA-GX8 Underwater Housing for Panasonic GX8

The Nauticam Housing for the Exciting GX8

Nauticam is pleased to introduce the latest in it's acclaimed line of underwater camera housings, the NA-GX8, designed specifically for the Panasonic GX8. Nauticam's unparalleled experience with taking mirrorless cameras underwater is evident in this exceptional housing. Nauticam supports more mirrorless cameras, and specifically more micro 4/3's cameras and lenses than any other manufacturer. 

The Panasonic Lumix DMC-GX8

Panasonic continues to push the m4/3 envelope, this time with a new sensor that breaks into the 20 megapixel realm, the highest of any m4/3 sensor to date. This camera is aimed squarely at the enthusiast, with it's excellent image quality, higher resolution, rangefinder styling and 4K video capture. It is an ideal camera for the underwater photographer/videographer.  

The GX8 also features "Dual IS", i.e. image stabilization in both the lens and sensor; working in concert to handle camera shake better than any previous Panasonic camera. More importantly for underwater image makers - focus has been improved considerably, especially in low light. Panasonic claims quick and accurate autofocus at -4EV. This should make focusing easier underwater, given that u/w scenes are typically darker than terrestrial scenes. The camera body features 3 command dials, including a dedicated exposure compensation dial.

Nauticam NA-GX8

The pioneering features of the earlier Nauticam housings are apparent with the simple but secure rotating housing latch and superb progressive shutter release providing optimal “feel”. The NA-GX8 also sports some of Nauticam’s latest technology with the port locking latch that replicates the famous Nauticam DSLR port latch – making housing port changes easier than ever. 

The new housing takes full advantage of the Panasonic's many features and allows easy one handed operation of key controls like the three command dials and the video record button. The NA-GX8 supports 7 programmable buttons on this camera, easily accessible from the housing. The sculpted shutter release makes "half-press" focus incredibly easy. For fans of “thumb focus” (moving the autofocus from half-press of the shutter to a button operated by the right thumb), this is fully supported with the AF/AEL button. 

Attention to detail is everywhere, from the comfortable thumb rest on the right to the large knurled command wheels and zoom/focus knob. Video is easily accessed; the video button is given special treatment, being larger, concave and red in color. For tripod use, the housing features two standard 1/4" 20 tripod holes, or is also tripod ready when using the Flexitray W camera tray. 

Strobe firing is supported via fiber optic through the use of the optional Panasonic DMW-FL70-S flash unit. Accurate automatic flash exposure (TTL flash) is easily accomplished via strobes like the Inon Z-240 or S-2000. 

The NA-GX8 comes standard with the Nauticam vacuum system electronic built in. By default, it serves as a audible and visual leak detector, but add a Nauticam M14 Vacuum Valve, (25611) and it becomes a vacuum check system - early warning for problems with watertight integrity - which means peace of mind when shooting underwater. 
 
Each control on the housing is clearly labeled, making it easy to learn the system. Milled from solid aluminum, the housing is rated to 100m/330ft depth, and is rugged and ready for use!

Nauticam's rotary locking latch mean secure yet easy access to changing batteries or memory cards. Why break your knuckles trying to open a housing?  

The Nauticam Port Locking Lever has become an icon; so easy to use yet more secure than lesser methods of attaching ports. No twisting required, just push & lock.  Worry less about the port attachment, and focus on getting great images. 

Green means Go! The Nauticam vacuum check system provides an extra safety check helkping to insure a watertight seal every time. 

The housing ergonomics are perfectly engineered for a "right hand on the grip" shooting style. Some users, especially those diving in cold water with dry gloves, need alternate ways to hold and operate the camera.

This included shutter release extension and stainless steel handle bracket provide convenient shutter release access when used with the Nauticam Tray and Handle Systems.

Lenses

It's all about the glass - lenses are the key to terrific photography. The m4/3 system supports a large range of high quality lenses produced by Panasonic (partnering with Leica), Olympus and third parties. Several lenses that perform extremely well underwater are available (and reasonably priced!). Some examples: 

• Olympus M.ZUIKO DIGITAL ED 12-50mm F3.5-6.3 EZ: The ultimate jack of all trades tool, this lens covers a very usable mid range, and features a unique macro mode. Shoot dolphins and nudibranchs on the same dive! 
• Panasonic Lumix G Fisheye 8mm/F3.5: This 180º fisheye lens focuses close and is razor sharp. Combines with a small port, there is no better CFWA (close focus wide angle) option on the planet. 
• Olympus M.ZUIKO DIGITAL ED 60mm f/2.8 Macro: This is an ideal macro lens for m4/3, and by adding the Nauticam CMC, it becomes a super macro monster. Imagine filling the entire width of the frame with something only 8mm wide!
• Panasonic Lumix G Vario 7-14mm f/4.0 ASPH: The 7-14mm is a rectilinear lens, ideal for shooting people or sharks or wrecks... subjects where the fisheye distortion is not welcome. On the wide end, this lens 114º wide, ideal for getting close to subjects to reduce the amount of water shot through. But a zoom gets to 75º - ideal for reaching out to that subject that is a little more skittish. The very similar Olympus M.Zuiko Digital ED 9-18mm f/4.0-5.6 can serve the same basic role at a lower cost.

There are many more options for the underwater photographer, including any of the several 14-42mm options, the Panasonic Lumix G X VARIO 12-35mm F2.8 ASPH. POWER O.I.S., Olympus M.ZUIKO DIGITAL ED 12-40mm f/2.8 PRO, Panasonic Lumix G Vario 12-32mm f/3.5-5.6 ASPH, Panasonic Lumix G 14mm F2.5 ASPH, and the Leica DG Macro Elmarit 45mm F2.8 ASPH. Olympus also recently released two new wide angle lenses that are superb for underwater use, the Olympus M.ZUIKO Digital ED 8mm f/1.8 Fisheye PROand theOlympus M.ZUIKO Digital ED 7-14mm f/2.8 PRO. 

Nauticam is the only underwater housing manufacturer to properly support ALL of these lenses. 

Nauticam Vacuum Check System

The Nauticam vacuum check and leak detection system electronics are included with the NA-GX8 as standard equipment.  Combined with an optional vacuum valve, this monitoring system provides constant updates on the water tight and safe to dive status of the housing. The operator can, at a glance, instantly see the water tight and safe-to-dive status of the housing. A simple coded LED lighting system lets the user know that the vacuum is solid, or that the housing is losing vacuum. Leak detection is built into the same circuit, so if there is water intrusion, an audible and visual indication will occur. The NA-GX8 features a 2nd bulkhead port (M14) specifically for installing optional vacuum valves, leaving the other bulkhead port for HDMI, sync cables and other accessories.
