The NA-A2020 is Nauticam's latest UW-housing for Sony's high-resolution full-frame mirrorless camera. Sony's full-frame camera also combines resolution with high speed shooting and fast autofocus capabilities to a fantastic degree.

Please observe that you find smart associated products at the bottom of the page as well as a short Swedish description.
Any other product are found in its specific categories.

The housing
The NA-α2020 features dual rear thumb-levers that are easily reached from the handle that access three of the most-used controls on the rear of the camera. The right lever actuates the AF-ON and RECORD buttons while the left lever is mapped to the PLAY button.

Atop the housing on the left side are controls specific to the a9II in the form of a MODE dial and FOCUS mode lever. The C1, C2 buttons as well as the EV compensation dial also have direct access from the top of the housing. The C3, which is typically assigned to control switching between the EVF and the LCD screen is easily reachable on the rear of the housing from the left handle.

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.

Ports and special optics
Nauticam's wide range of ports and in-house corrective optics are the perfect compliment to the NA-α1's inherent flexibility. Built around the N100 Port System, the NA-α1 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-1B.
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

Strobe 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.

Nauticam produces a “straight” 180º enhanced viewfinder and a 45º angled enhanced viewfinder to enhance the ease of close quarters work often associated with macro shooting. Both viewfinders have high quality optics, and allow bright viewing of the entire image.

Vacuum system
The Nauticam vacuum check and leak detection system is shipped with NA-A7RIV as standard equipment. Combined with an accessory vacuum valve (#25624), this monitoring system provides constant updates on the water tight and safe-to-dive status of the housing.
