NAUTICAM LENS & PORT CHARTS

Nauticam Fujifilm GFX 100 Underwater Housing NA-GFX100

The GFX, Fujifilm’s mirrorless digital camera system, has achieved the highest level of image quality in the world of professional photography. The GFX100 uses a 55mm diagonal length large format CMOS sensor with over 100 million pixels which makes this the highest class resolution mirrorless digital camera ever produced. The Nauticam NA-GFX100 and the N120 Port System supports the dedicated lineup of GF lenses.
 

FUJIFILM GFX 100

The Fujifilm GFX 100 is equipped with a 102MP sensor which is 1.7 times larger than that of a 35mm full-frame sensor. It offers fast and reliable autofocus, in-body image stabilization, and 4K video capability. Built for extreme environments, the GFX 100 is weather resistant and freeze proof to -10ºC.

THE NA-GFX100 UNDERWATER HOUSING

Nauticam has produced housings for a variety of both medium format and mirrorless housings. The NA-GFX100 takes all that experience and produces the most ergonomic housing available for a mirrorless digital medium format camera. Nauticam has continued to offer unencumbered access to the essential controls that underwater photographers need.

The GFX 100 has 15 customizable buttons. The camera's "Q" menu can also be customized to accommodate the most-used menu items. The "Q" menu is easily accessed by the double thumb-lever on the right-hand side which also accesses the "AF-ON" button critical for back button focus. The left-hand double thumb lever accesses the "PLAY" and "DISP/BACK" functions.

The directional keys on the right-hand side engage the joystick to easily change the focus points. The GFX 100 has a total of 3.76 million phase detection autofocus points. Above the directional keys is a rotating lever that allows you to quickly change the focus mode.
 

FLASH TRIGGERING

Flash triggering is performed via built-in fiber optic bulkheads using the Fujifilm EF-X20 TTL flash which fits into the housing when mounted on the hot-shoe. Flash EV can be controlled via a dial atop the housing and status can be seen through dedicated viewports. The flash can be turned on and off via a lever on the left side of the housing.
 

PREMIUM PROFESSIONAL OPTICS

The GFX 100 uses a new lineup of dedicated lenses with the moniker GF. The Nauticam N120 Port Systems supports many of those currently available including ultra-wide primes, zooms, and macro lenses.
 

VIEWFINDERS

The standard optical glass viewfinder is very good and travel-friendly, but many photographers prefer the ease of a magnified viewfinder with an adjustable diopter. Nauticam produces a “straight” 180º enlarging viewfinder and a 45º angled enlarging viewfinder to enhance the ease of close-quarters work often associated with macro shooting. 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.
 

INTEGRATED VACUUM CHECK AND LEAK DETECTION SYSTEM

The Nauticam vacuum check and leak detection system is shipped with NA-GFX50S as standard equipment. Combined with an accessory vacuum valve this monitoring system provides constant updates on the water-tight and safe-to-dive status of the housing. A simple color-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 Nauticam system is temperature compensated, eliminating false alarms caused by a change in outside temperature, or from a camera heating up on an action packed dive.
 

FEATURES

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 LATCHES

The industry's easiest to use housing closure system, requiring very little hand strength to operate, secures the housing back in place. The latches are safely locked to prevent accidental opening but are easy to open when needed for a quick battery or memory card change.
 

DOUBLE THUMB LEVERS

The NA-GFX100 has double thumb levers on each side. The left side pair accesses Playback and DISP while the right side pair brings up the Q menu and activates the autofocus.
