NA-XT5 FOR FUJIFILM X-T5 CAMERA

The X-T5, Fujifilm's latest APS-C mirrorless hybrid camera, adds alis of significant upgrades when compared to its predecessors. Some of the most noticeable improvements are a new 40.2MP sensor with a processor 2x as fast as the X-T4. As still/video hybrids become more popular, Fuji is offering a high-resolution camera that can record internal 6.2K 10 bit 4:2:2 video or 12 bit ProRes RAW externally over HDMI in addition to shooting an impressive 20fps of continuous stills.

Technical Specifications

Introducing NA-XT5

Fujifilm X-T5

The Fujifilm X-T5 features an APS-C CMOS 4 X-Trans 5 HR BSI 40MP Sensor. The X-T5 is powered by a new X Processor 5 which provides extremely fast performance and improved responsiveness. Improved in-body stabilization delivers up to a 7EV benefit which is a significant benefit for video shooters. The intelligent 425 point hybrid autofocus tracking system is now sensitive down to -7EV allowing it accurately focus in extreme low light conditions.  

The X-T5 allows you to record oversampled 6.2K 30p or 4K 30p with a 1.23x crop factor or subsampled 4K 60p with the full width of the sensor. When combined with the Atomos Ninja V, the X-T5 can output up to 6.2K 12 bit ProRes RAW. Like the X-T4, the X-T5 also features HLG and F-Log capture to increase dynamic range, protecting highlights and shadows for editing. New to the X-T5 is F-Log2 which provides you with 13+ stops of dynamic range instead of just 12 stops with F-Log.

The Nauticam NA-XT5 Underwater Housing

Nauticam has supported all the previous X-T cameras and continues to create innovative and ultra-functional housings for this line with the NA-XT5 underwater housing. The NA-XT5 features DSLR-style housing and port lock mechanisms as well as integrated ergonomic 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-XT5 features thumb levers near both handles, with the left thumb lever actuating the playback function and the right thumb lever the AF-ON control. The housing includes two M14 and one M24 bulkhead openings to accommodate a variety of accessories.

The NA-XT5 uses the N100 Port System shared with the Fujifilm XH1, XT3 and XT4 system. A selection of port options are available for a variety of lenses.

Premium Professional Optics

Nauticam's wide range of ports and in-house corrective optics are the perfect compliment to the NA-XT5's inherent flexibility. Built around the N100 Port System, the NA-XT5 supports a wide variety of X-mount lenses. In addition, there are several options available to use the groundbreaking WACP-1 and WACP-C wide-angle corrective lenses as well as the more compact and in-water removable WWL-1B and WWL-C.

For example, with the Fuji XF 18-55mm f/2.8-4 R LM OIS lens, the WACP-1 brings the original 75º field-of-view to an impressive 130º with sharper corners, an ~0" minimum focus distance and a more natural looking image than would be provided by a standard glass dome port. For complete water contact lens compatibility, you can view the port chart here.  

HDMI 2.0

A large bore M24 bulkhead is located at the front of the housing for use with HDMI 2.0 or HDMI 1.4 (with a step-down adapter to M16) external monitors and recorders. The X-T5 can output up to 6.2K 12 bit ProRes RAW over HDMI 2.. See the resources sidebar for additional details and recommended setups.

Flash Triggering

Reliable automatic flash exposure is available with the NA-XT5 and a variety of optically fired flashes, precisely reproducing the Fujifilm 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-XT5 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-XT5 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.

External Battery Pack

The NA-XT5 housing supports the use of an USB-C battery pack in order to greatly extend the time between battery swaps, and allowing the housing to remain sealed between dives. The battery compartment at the bottom of the housing supports batteries up to 150mm(W) x 18mm (H) x 72mm (D).  Here is a known compatible battery with more to come

• Anker USB-C Portable Charger 10000mAh with 20W Power Delivery, 523 Power Bank (PowerCore 10K). (180min of additional run time

25303 USB-C to USB-C Right Angled Cable (in 0.5m length) is recommended for use with USB-C battery packs. 

Integrated Vacuum Check and Leak Detection System

The Nauticam vacuum check and leak detection system is pre-installed in the NA-XT5 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.
