Nauticam Underwater Housing for Sony A7RIV and A9II Cameras
The Nauticam NA-A2020 Housing for Sony A7RIV and A9II Cameras
A professional housing befitting of a two top-of-the-line cameras, offering support for both the Sony a7RIV and a9II cameras in the same housing without modification.
Sony A7R IV and A9 II Cameras
While both the a7R IV and the a9 II feature the same size sensor and body, they are two very different cameras. With the NA-α2020 Underwater Housing, you now can choose the right camera for the job while using the same housing, lenses and ports. Both cameras share 5-axis in-body stabilization (IBIS) providing up to 5.5 stops of stabilization and the ability to record 4K video either from the full sensor width or a Super35 crop at up to 30p to dual UHS-II SD card slots. Both cameras are capable of clean HDMI video output up to UHD 4K 4:2:2 8-bit at up to 25p.
The NA-Α2020 Underwater Housing
Nauticam has supported the Sony Alpha full-frame line since the original a7 with professional grade aluminum housings that offer intuitive access to all the controls and functions of the cameras. As the cameras have evolved, so have the Nauticam housings. The Nauticam NA-α2020 takes our commitment to the Sony full-frame mirrorless line to another level by delivering the first housing that will support both the a9 II and the a7R II with full access to all controls without modification or restriction. Integrated DSLR-housing styled handles with ergonomic rubberized grips and stainless steel stiffening brackets add stability and accessory mounting points. The NA-α2020 also 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 - HDMI 2.0 Ready
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.
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.
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) or UW Technic's TTL board (uwt-11075).
