Nauticam NA-FX3 for Sony FX3/FX30

Looking at the specs, the Sony FX3 is strikingly similar to the A7S III less an electronic viewfinder.  Take a closer look and its the powerful video features of the FX3 with cinema-centric controls and exterior design.  The FX3 can capture 4K at up to 120fps with 15+ stops of dynamic range with the option for RAW over HDMI.  Controls are optimized for video with direct iris, ISO and shutter angle control.  With the addition of an internal fan, the recording time limit for 4K60p has been removed.  The NA-FX3's compact size make it ideal for the traveling filmmaker and those looking for a more nimble underwater system.

The Nauticam NA-FX3 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-FX3 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.

The NA-FX3 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-FX3 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.

Optical performance is just as necessary as camera performance and this becomes even more critical given the challenges of filming underwater. The Nauticam NA-FX3 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.
