AquaTech EDGE Waterproof Housing for Sony a7S III Camera - Professional Underwater Photography & Videography Gear for Diving, Surfing & Marine Exploration

This AquaTech EDGE Sony a7S III Conversion Kit lets you use your camera in an Aquatech EDGE Sport housing originally designed for a different model. It contains a dedicated backplate with camera controls, a camera plate, and a dedicated cable release, all compatible with the a7S III.

The great advantage of using a conversion kit is that you can cross between camera models or manufacturers without needing to purchase a new water housing if you upgrade your camera or would like to use two different cameras in the water for different reasons.
