Nauticam NA-A2020 housing for Sony A9II/A7RIV / HDMI2

Accessory ports
The NA-α2020 has both and M24 port at the front of the housing for both HDMI 1.4 and HDMI 2.0 connectivity (see sidebar for recommendations) as well as an M14 at the rear for the optional Vacuum Valve (25624).  The housing comes with electronics pre-installed for Nauticam's Vacuum Check and Leak Detection system.  This monitoring system 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
Nauticam's wide range of ports and in-house corrective optics are the perfect compliment to the NA-α2020's inherent flexibility.  Built around the N100 Port System, the NA-α2020 supports a wide variety of Sony FE mount lenses, as well as EF mount lenses via adapters.  In addition, there are several options available to use the groundbreaking WACP and WACP-2 wide-angle corrective lenses as well as the more compact and in-water removable WWL-1.  

For example, With the Sony SEL1635GM FE 16-35mm F2.8 GM, the WACP 2 brings the original 105º field-of-view to an impressive 128º with sharper corners, an ~0" minimum focus distance and a more natural looking image than would be provided by a standard glass dome port.

Flash triggering
Both fiber-optic and electrical strobe triggering options are available.  The Nauticam Universal Fiber Optical cables attach to the built-in bulkheads atop the housing and feature modular connections for both Sea&Sea-style bushings and INON threaded connections.  Triggering is achieved using the optional Nauticam Mini Flash Trigger for Sony (26302) which uses LEDs powered by an on-board coin-cell battery to generate a manual signal that is transmitter via the optical cables to compatible strobes.
