Innovation, ergonomics, and reliability are the hallmarks of the Nauticam brand.

Nauticam Fujifilm NA-XT3 Underwater Housing for Fujifilm X-T3 Mirrorless Camera

Fujifilm's third generation X-Trans APS-C mirrorless camera, the X-T3, has significant upgrades in regards to autofocus and video capabilities.  While still and video hybrid cameras continue to become more popular, Fujifilm is raising the bar with a 26MP, high-resolution electronic viewfinder camera that can record internal 10 bit 4:2:0 H.265 DCI/UHD 4K video or 4:2:2 over HDMI as well as shooting an impressive 20fps of continuous stills.

Nauticam has supported X-T1 and X-T2 cameras and continues to create innovative and ultra-functional housings for this line with the NA-XT3.  More than just an updated badge, the NA-XT3 is a complete redesign of the series.  With a form factor more closely resembling the NA-A9 for Sony's A9 mirrorless camera, the NA-XT3 features DSLR-style housing and port lock mechanisms as well as integrated ergonomic handles.  An optional hand strap (PN 28130) can be added to the handles.  The housing is designed with our Mission Control concept of placing the most important camera controls as close to the handles as possible to facilitate effortless and quick camera operation to ensure you don't miss the shot.

The NA-XT3 features thumb levers near both handles, with the left thumb lever actuating the playback function and the right thumb lever the AF-L control.  The housing includes two M14 and one M24 bulkhead openings and an M5 threaded hole on top (underneath the cold shoe) for an additional ball mount.

The NA-XT3 uses the N100 Port System shared with the Fujifilm XH1 system.  A selection of port options are available for a variety of lenses.

Video Recording Features

The impressive video specs of the X-T3 prompted the addition of some video-centric features to the NA-XT3.  The base of the housing can accept Nauticam's Mounting Ball Set for Tripod (PN 25218), the same part as for the NA-A9.  

As the X-T3 can output DCI/UHD 4K at 60p with 4:2:2 quality over HDMI, a new M24 bulkhead has been incorporated into the housing to support an HDMI 2.0 connection to the Nauticam Atomos Ninja V housing (HDMI 2.0) for Atomos Ninja V 5” 4Kp60 4:4:2 10-bit Recorder/Monitor/Player (17922).

Video shooting can decrease battery life so the NA-XT3 is compatible with an optional 2500 mAh USB-C Battery Pack (PN 36335) that sits below the camera tray inside the housing.

Flash Triggering

Reliable automatic flash exposure is available with the NA-XT3 and a variety of optically fired flashes, precisely reproducing the camera’s included EF-X8 flash at a proportionally greater intensity. This system yields accurate automatic TTL flash performance – even in manual exposure mode – with no electrical sync cables to flood!

The NA-XT3 is also compatible with the Nauticam Mini Flash Trigger for Panasonic/Fujifilm (PN 26305). The Flash Trigger allows for rapid fire manual flash firing via fiber optic, with no camera battery drain.

The NA-XT3 comes fiber optic ready and accepts standard Sea & Sea style bushing connections.

Integrated Vacuum Check and Leak Detection System

The Nauticam vacuum check and leak detection system is pre-installed in the NA-XT3 as standard equipment. Combined with an optional M14 Vacuum Valve II (PN 25624), this monitoring system provides constant updates throughout the dive as to watertight integrity of the housing via a multi-color LED on the rear of the housing.
