With the A7SIII, Sony introduced the highest resolution full frame mirrorless camera to date and with the A7SIII it took speed image quality to another level.

NAUTICAM NA-A7SIII (17428)

Nauticam is the leader in producing intuitively designed precision manufactured aluminum underwater housings for the Sony a7 camera line and continues to innovate with the new NA-A7SIII housing. 

The NA-A7SIII is designed to maximize the video-centric capabilities of the Sony a7S III camera while maintaining it's strong still image potential. The NA-A7SIII is built around the N100 port system that is shared with the rest of the Nauticam housing lineup for the Sony full-frame mirrorless a7 series. The N100 system includes a dull range of both macro and wide-angle ports as well as delivering access to the lineup of Nauticam's professional wet optics that are optimized for underwater imaging such as the WACP-1/2 and the SMC-1/2 lenses. These optics deliver unparalleled image quality underwater expanding what is possible with the powerful a7S III camera.

HDMI Output

The a7S III can output 16-bit raw video signal over HDMI and the NA-A7SIII features an M24 bulkhead that supports the HDMI 2.0 standard.  This allows the NA-A7SIII to be used in conjunction with either a recording monitor such as the Atomos Ninja V in the NA-NinjaV housing  via HDMI 2.0 or standalone monitors such as the SmallHD 502 Bright in the NA-502B housings via HDMI 1.4.  

Optional Magnifying Viewfinder

The a7S III camera features an updated 9.44M-dot OLED viewfinder with a 120fps refresh rate. Nauticam's line of optional magnifying viewfinders, available in both an angled 45º (32203) or straight 180º (32201) configuration provide enhanced viewing ability as well as a dioptric adjustment knob that can used underwater. Installation can be achieved without tools in less than a minute.  

Mission Control

Nauticam engineer's Mission Control design philosophy means controls are intuitively placed where they are needed most regardless of their position on the camera. The NA-A7SIII features a double thumb lever within easy reach of the right handle that triggers the AF-ON and RECORD controls of the camera. A thumb lever on the left side toggles the PLAYBACK button. The back panel of the housing provides access to all other rear camera controls including a multidirectional pad.

Vacuum Check and Leak Detection System

The Nauticam vacuum check and leak detection system is shipped with NA-A7SIII as standard equipment. With the addition of the optional M14 Vacuum Valve (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.

Patented port locking system

Unveiled on the very first Nauticam DSLR housing in 2009, this locking lever has become a signature of the Nauticam brand.  No twisting or threading action is required to mount a port, and it locks securely in place with this lever.  Nauticam also offers locking port extensions, meaning a dome will never twist, even when used with a long extension ring.

Housing locking latches

The industry's easiest to use housing closure system, requiring very little hand strength to operate, secures the housing back in place. The latches are safely locked to prevent accidental opening, but are easy to open when needed for a quick battery or memory card change.
