The housing

The housing 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 a9III 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

It 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-α9III inherent flexibility. Built around the N100 Port System, the NA-α9III supports a wide variety of Sony FE mount lenses, as well as EF mount lenses via adapters. The NA-A9III can leverage the unparalleled optical quality of Nauticam's Water Contact optics such as the FCP-1, WACP-1 or WWL-1B which offers up to 170º field-of-view, full zoom through, an almost 0" minimum focus distance with supported lenses. For macro, the SMC-1 and SMC-2 deliver tack-sharp super-macro magnification levels up to 4x with the Sony 90mm macro lens.

Lens port is required

A compatible lens port is required for underwater use (sold separately). Choose the correct port components for the lens you will be shooting.

Strobes

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.

The Nauticam vacuum check and leak detection system is shipped with the housing 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.
