The Panasonic Lumix DMC-GX8
Panasonic continues to push the micro four thirds envelope, this time with a new sensor that breaks into the 20 megapixel realm, the highest of any MFT 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.
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 underwater scenes are typically darker than terrestrial scenes. The camera body features 3 command dials, including a dedicated exposure compensation dial.

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 (requires 71209 Adjustable Right Handle and 71208 FlexiTray II W with Left Handle). 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.
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.
Flash Connectors for Inon S-TTL
Reliable automatic flash exposure is available with the NA-GX8 and a variety of optically fired flashes. The Inon Z-240, D-2000, S-2000 strobes provide automated lighting, precisely reproducing the camera’s onboard flash at a proportionally greater intensity. This system yields accurate automatic TTL flash performance – even in manual mode – with no electrical sync cables to flood! The NA-GX8 comes fiber optic ready and accepts standard Sea & Sea style bushing connections. Nauticam Fiber Optic cables, available for both Inon and Sea & Sea strobes, provide the best light transmission and therefore more accurate TTL of any fiber optic cable on the market.
The standard optical glass viewfinder is very good and travel friendly, but many photographers prefer the ease of a magnified viewfinder with adjustable diopter. Nauticam produces a special version of it’s enhanced viewfinders made specifically for it’s new line of mirrorless camera housings. Whether it’s the “straight” 180º enlarging viewfinder (32204) or the 45º angled enlarging viewfinder (32205), the enlarged and brighter view enables easier focusing. Both viewfinders have high quality optics, and allow bright viewing of the entire image. 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.

Patented Port Locking System
Unveiled on the very first Nauticam DSLR housing in 2009, this locking lever has become a signature of the Nauticam brand. No twisting or threading action is required to mount a port, and it locks securely in place with this lever. Nauticam also offers locking port extensions, meaning a dome will never twist, even when used with a long extension ring.
Housing Locking Latch
The secure single rotating housing latch opens the housing back allowing for quick and easy battery or media changes.
Nauticam engineers strive to make all the essential exposure controls readily accessible from your natural hand position to turn your housing into Mission Control for your underwater imaging.
Accessory Mounting Options
The NA-GX8 features a cold-shoe mount as well as an M5 threaded mount allowing you to mount additional accessories in addition to an M14 and M16 bulkhead.
