Sony Alpha a1 II, a9 III - Nauticam NA-A1II Housing - 17438

The NA-α1II Housing

The NA-α1II Housing is based on the Nauticam NA-a9III housing and can accommodate both the Sony a1II and a9III camera bodies with no adapters of modifications.  This truly makes this housing one of the ultimate underwater imaging tools able to capture high resolution as well as low-light stills and high resolution, low-noise and high-framerate video.

Mission Control

The driving force behind Nauticam housings is to place controls where they should be, within easy reach of the ergonomic handles for an intuitive and smooth underwater filming experience.  The NA-α1II features a dual action thumb lever on near the right handle that actuates the 'AF-ON' and 'REC' buttons.  Near the left handle is a thumb lever for 'PLAYBACK'.  The shutter release, main and sub command dials are also all within easy reach without taking your hands off the handles.

Professional Optics

The NA-α1II housing is built around the N100 port opening allowing for a wide variety of optics solutions from extreme wide-angle to super macro.  In addition to supporting traditional wide angle dome port and macro flat-port configurations, the NA-α1II can support much of Nauticam's range of Water Contact Optics from the Fisheye Conversion Port (FCP) to the Extended Macro Wide Lens (EMWL).  To truly unlock the creative possibilities of these two cameras, pairing them with either the WACP-1B, WACP-C or WWL-1B gives impressive 130º rectilinear field-of-view, ~0" minimum focus distance, full zoom through capabilities and the incredible corner sharpness.  If more coverage is needed, the FCP provides 170º fisheye coverage with full zoom through and close focus capabilities.  Take your macro imaging to the next level with either increased 2.3X magnification with the new SMC-3 close-up lens or the wide-angle macro look of the EMWL 160º lens.

EVF Enhancement

Both the Sony A1II and A9 III feature the same ultra-high resolution 9.4M-dot electronic viewfinder (EVF). To truly take full advantage of this underwater consider pairing it with one of the Nauticam Enhanced 0.8:1 Viewfinders.  These underwater viewfinders are designed to give full edge-to-edge magnified viewing and include a diopter that can be adjusted underwater to match your vision.  ​

HDMI 2.0

A large bore M24 bulkhead is located at the front of the housing for use with HDMI 2.0 or HDMI 1.4 (with a step-down adapter to M16) external monitors and recorders.  An additional M10 threaded mounting position near the front center of the housing also makes using an external monitor even easier. 

Build Quality

Nauticam build quality is simply unmatched, using cutting-edge product design and modern, innovative manufacturing techniques that result in trouble-free reliability. A bit like a fine Swiss timepiece, the complexity under the hood results in a trouble-free user experience that just works, and keeps working for years to come.

Flash triggering

Please set the "Sync Terminal Settings" to always, then camera can output a flash signal to the Multi Interface Shoe when shooting. 

MENU -> (Exposure/Color) -> (Flash) -> (Sync Terminal Settings) -> Always

Integrated Vacuum Check and Leak Detection System

The Nauticam vacuum check and leak detection system is shipped with NA-A9III as standard equipment. Combined with an accessory vacuum valve (PN 25624), 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.
