In the past when we discussed medium format cameras we typically thought about large cameras best suited for studio photography. Fujifilm has turned this around with the GFX 50S. With it's mirrorless design the GFX 50S is not much larger than your average full frame DSLR. When housed in the Nauticam NA-GFX50S the system is only slightly bigger than a NA-D850 or NA-5DMKIV.

The GFX camera system is built around the 43.8 x 32.9mm 51.4MP CMOS sensor. It produces 14-bit high resolution files with an extremely wide dynamic range of 14 stops, as well as an extended sensitivity range of ISO 50-102400. The large sensor achieves a unique three-dimensional look with smooth color transitions. Like Fujifilms X-series cameras, it offers retro-styling direct controls but can also be configured to operate like a typical DSLR using the control dials. The GFX has 3 fps continuous shooting, Fujifilm Film Simulation modes and is also capable of capturing Full HD video at up to 30p.

The NA-GFX50S is the first housing for a mirrorless digital medium format camera. It offers unencumbered access to the essential controls that underwater photographers need.

The GFX50S has 10 customizable buttons. The camera's "Q" menu can also be customized to accommodate the most-used menu items. 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.

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 on top of 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.

The GFX 50S uses a new lineup of dedicated lenses. The Nauticam N120 Port Systems supports many of those currently available including ultra-wide primes, zooms, and macro lenses. The Wide Angle Conversion Port WACP can be used with the GF 45mm f/2.8 R WR lens.

The NA-GFX50S accepts the Nauticam 180º straight enlarging viewfinder or the 45º angled enlarging viewfinder. Both viewfinders have high quality optics, and allow bright viewing of the entire image.
