NAUTICAM NA-A7SIII UNDERWATER HOUSING 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 (NA32201) 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 (NA25624) 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.

With each new generation of camera, Sony continues to make giant strides in the way images are taken and processed.  The Sony a7R V shares the same 61MP sensor as the previous a7R IV, however it has made huge advancements in processing capacity which brings improvements across the board.  With a newly developed AI processing unit, the Sony a7R V brings an all new autofocus system which builds upon more intelligent subject tracking and recognition.   The a7R V features 8 stops of image stabilization and an impressive array of video capabilities including 8K 10-Bit internal recording and 16-Bit RAW external recording over HDMI which are sure to make this a popular choice among underwater shooters. The Sony alphy 7R V Camera The Sony a7R V is Sony’s fifth generation, high-resolution full-frame mirrorless camera. The 61.0-megapixel full-frame back-illuminated Exmor R CMOS sensor combined with BIONZ XR imaging engine delivers unprecedented resolution, fine gradation, and low noise at a processing speed increased by 8x that of the a7R IV. Relative to previous generations, it promises more robust build quality, refined controls, and the company's latest autofocus. The new processor brings the power to significantly enhance the camera's subject recognition capabilities for auto focus. The a7R IV had the ability to recognize and prioritize people, their faces and eyes, but the a7R V takes this much further. The a7R V is designed to better recognize human subjects but also trained to recognize a wider range of non-human subject types. In addition to 8K shooting, 4K video is oversampling from 6.2k pixels without binning, to deliver maximum detail, and offers up to 60p shooting and S-Cinetone for superior cinematic expression. The camera also gives the creative freedom to continuously shoot up to 583 compressed RAW images at 10 fps.
