Sony's new flagship full frame camera is a marriage of speed and image quality. A huge 50 megapixel stacked CMOS sensor with a secret new 'high speed processing circuit' are now packed into what still looks and feels like any other Sony Alpha camera to date. Sony also introduces a new lossless RAW compression format which makes file storage faster and more efficient than shooting uncompressed RAW.
Sony has also improved their formidable autofocus engine with twice as many AE/AF calculations per second compared to 2019's a9 II model. This combined with improved noise reduction provides incredibly fast and accurate autofocus, even when shooting at the smaller apertures desirable in underwater photography.
The electronic viewfinder (EVF) is the highest resolution available to date at 9.44 million-dots.
On the heels of Canon's EOS R5, the Sony a1 offers professional grade 8K stills and video capture and an improved heat dissipation design. If you're willing to drop down to 4K you can take advantage of the digital Active Steadyshot stabilization on top of the 5.5EV mechanical in-body stabilization. Sony Alpha a7S III Mirrorless Cameras
Five years after the release of the A7S II, Sony made good on its promise for a successor. This powerful full frame mirrorless is built for the serious videographer with a newly developed BIONZ XRâ„¢ image processing image and a new 12.1MP back-illuminated Exmor Râ„¢ image sensor, significantly reducing rolling shutter.
Exceptional low light performance is good news for the underwater videographer with ultra-high sensitivity expandable 80-409,600 ISO range and 15 stop dynamic range for movies.
A new heat dissipation system makes continuous 4K/60p recording up to 'at least' one hour possible. This is achieved without fans or cabinet vents to keep the camera dust and moisture resistant.
A fast Hybrid AF system has 759 phase-detection AF points covering 92% of the image sensor. Sony claims the camera can deliver fast and accurate autofocus at light levels so low that the human eye struggles.
Hard core videographers will want to take some time with camera's impressive list of specifications including 16-bit RAW output at up to 60p and 10-bit 4:2:2 internal capture (in codecs including H.265 and All-I H.264).
Lens Ports
This housing features our robust Dry Lock (DL) port system. "Dry Lock" refers to the placement of the o-ring on the outside of the port mount. This improves visibility and reduces the chances of water dropping onto your precious camera sensor. DL ports are the lightest on the market, yet robust and capable of standing up to rough surf. Attachment is quick and secure. A system of extensions can accommodate a huge variety of lenses with ease.
Most popular lenses and select lens focus rings can be engaged using simple gearing that puts adjustment right at your fingertips. A large, soft-touch knob on the side of the housing makes fine tuned adjustments a breeze. and focus gears differ depending on which lens you are using. gears sold separately.

The unique rear seal design prevents accidental twisting or stretching of the o-ring for simple and confident assembly. We have eliminated the need for an o-ring groove or channel which can trap sand, dirt, or debris. Three double-passivated stainless steel locking lid snaps are simple to use and virtually unbreakable. The clear back allows you to see the o-ring form a solid, watertight seal as it closes. Vacuum Testing
A vacuum valve is installed standard on the side of the housing. The vacuum valve is designed to be low profile to avoid interference with controls. The optional Vacuum Pump with Gauge # 47011 allows you to draw a vacuum on the housing to check for leaks prior to entering the water.
Drawing a vacuum on the system also provides extra security at the surface of the water, especially important when using the housing in rough surf. M16 Accessory Port
The spare M16 threaded accessory port provides an attachment point for third party accessories including HDMI bulkheads. TTL Exposure
