Press release

Introducing NA-XT3


The Fujifilm X-T3 features an APS-C CMOS 4 X-Trans 26.1MP Sensor. The X-T3 is powered by an upgraded X Processor 4 that is 3x faster and allows for 1.5x faster sensor readout than the X-T3. The base ISO has been lowered from 200 to 160. Oversampled DCI or UHD 4K (using full sensor width) is possible at 30p whereas 60p can be recorded with a minor 1.18x crop. The 60p footage can be captured as 10 bit 4:2:0 H.265 at 200 Mbps and recorded internally. This increases to 4:2:2 when output over HDMI. The X-T3 also features F-Log capture to maximize dynamic range, protecting highlights and shadows for editing. The X-T3 features a Natural LiveView mode when recording F-log that more closely resembles a standard monitoring LUT. Zebra warnings and focus peaking overlays, as well as magnification during shooting, are all improvements that video shooters will appreciate. Three custom white balance slots are available in addition to the 7 presets.

The electronic viewfinder of the X-T3 is vastly improved with 3.69M dots as compared to the 2.36M dots of the X-T2. Battery life has also been improved. The X-T3 can achieve 20fps continuous shooting with Autofocus and this increases to 30fps when shooting from a 1.25x crop area. A Sport Finder mode will show this cropped area inside the EVF.

Phase-detection autofocus has been increased to 98% of the sensor area.

The X-T3 also features a fast 1/250 X-sync speed.

Key Camera Specifications


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 is 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. Nauticam Universal fiber optic cable system (PN 26216) for Inon, Sea&Sea strobes, provide exceptional light transmission for accurate TTL performance.

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.

Key Features

Housing Locking Latches

The industry’s easiest to use a 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.

M24 HDMI 2.0 Bulkhead

A new M24 bulkhead has been incorporated into the housing to support an HDMI 2.0 connection to the Nauticam Atomos Inferno housing for Shogun/Ninja Inferno 7” 4K60 4:2:2 10-bit recorder/monitor.

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.

Accessory Battery Extender

The NA-XT3 can be used with the optional 2500 mAh USB battery pack (PN 36335) that rests in a form-fitting cradle beneath the camera and can be easily removed for charging.

Mission Control

The NA-XT3 places important camera controls as close to the handles as possible to ensure effortless and quick camera setting changes underwater to ensure you don’t miss the shot. Thumb levers for playback and AF-L are within easy reach.

Ergonomic Rubberized Grips

Another legendary Nauticam feature, these rubberized grips have been used every Nauticam DSLR housing release and are now a feature on the NA-XT3. The zoom/focus control knob also features this same soft-touch rubber coating for an improved tactile feel.
