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.
Key Camera Specifications
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 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 auto focus points. Above the directional keys is a rotating lever which 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 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.
