Nauticam FX5 Underwater Housing for Sony FX5 Full-frame Cinema Line  Now Accepting Preorders – Expected to Ship Mid-September 2026 The Sony FX5 delivers flagship cinema performance in a remarkably compact body. Featuring a newly developed full-frame, fully stacked Exmor RS CMOS sensor, the powerful BIONZ XR2 image processor, and a dedicated AI processing unit, the FX5 offers exceptional image quality, speed, and autofocus performance for professional filmmakers. With more than 15 stops of dynamic range in S-Log3, three native base ISO settings, and Sony's new Dual Gain Shooting mode, the FX5 captures outstanding highlight and shadow detail across a wide range of shooting environments. It also becomes the first camera in the FX lineup to support full-frame 3:2 Open Gate recording and internal 16-bit X-OCN RAW recording, eliminating the need for an external recorder. For underwater filmmakers, this means the entire recording workflow can now be contained inside a single housing.   Key Features New full-frame, fully stacked Exmor RS CMOS sensor with BIONZ XR2 image processor and dedicated AI processing unit Over 15 stops of dynamic range in S-Log3 Triple native base ISO settings: 800, 4000, and 12800 New Dual Gain Shooting mode for improved shadow detail and reduced image noise 3:2 Open Gate recording with full sensor readout Additional recording modes include 17:9, 16:9, and Super 35 scan formats Internal 16-bit X-OCN RAW recording with new X-OCN C1 and C2 compression options Recording up to 5K at 60 fps, 4K at 120 fps, and Full HD at 240 fps AI-powered Real-time Tracking autofocus with advanced human pose estimation 5-axis in-body image stabilization with approximately twice the roll correction performance of the FX3   THE NAUTICAM NA-FX5 UNDERWATER HOUSING The Nauticam NA-FX5 is designed to deliver an intuitive user experience in a rugged and reliable platform that is supported by the extensive Nauticam lineup of accessories and premium optics. The NA-FX5 is built around the N100 port system that is shared by all full-frame Sony mirrorless systems in the Nauticam lineup, allowing seamless crossover for existing Sony shooters.   CAMERA COMPATIBILITY The NA-FX5 underwater housing is compatible with the Sony FX5 Cinema Camera MISSION CONTROL The NA-FX5 is designed with our Mission Control philosophy, placing controls where they can be easily accessed with minimal movement.  Within easy reach of the right handle are control dials for Iris, ISO and Shutter Speed.  There is also a dedicated REC button and FOCUS MAG lever.  Stainless steel stabilizing brackets insure the handles remain steady even when using large video lights or other accessories. CONNECTIVITY The NA-FX5 features a an M24 bulkhead which supports the Nauticam HDMI 2.0/1.4 cable system which can be paired with supported external monitors/recorders.  In addition there is an M16 bulkhead which is dedicated for remote control capability using the Sony RM-VPR1 controller (proprietary waterproof cable is required).  On the rear cover there is also an M14 bulkhead which can be fitted with the optional M14 Vacuum Valve II (25624).  The NA-FX5 comes with the Nauticam vacuum check and leak detection system as standard equipment. This monitoring system, when paired with the optional vacuum valve, 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. PREMIUM PROFESSIONAL OPTICS Optical performance is just as necessary as camera performance and this becomes even more critical given the challenges of filming underwater. The Nauticam NA-FX5 uses the same N100 Port System as other Sony full-frame mirrorless housings which makes for a seamless transition for those upgrading or looking to add an additional camera to their lineup. While this system provides exceptional optical-glass and flat port solutions for a wide variety lenses, the real power can be realized using Nauticam's Water Contact Optics. This lineup of dry and wet lenses are conceived using commercial lens-design software to achieve truly unparalleled underwater image quality both for stills and video in both macro and wide-angle situations. The WACP-1 and WACP-2 achieve ultra-wide 130º fields-of-view with reduced distortion over conventional optics while featuring ~0" minimum focus distances, zoom through capabilities and unbeatable corner sharpness at even wide-open apertures such as F5.6.
