Sea & Sea MDX-A7III Underwater Housing for Sony A7III and A7RIII

You can capture the beauty of sea life and environments at depths as great as 328' with your Sony a7III or a7RIII mirrorless camera, thanks to the black Sea & Sea MDX-A7III Underwater Housing. It comes equipped with fiber-optic and sync cord strobe connectors and supports the optional, internal Optical Converter S1, which provides TTL capability with Sea & Sea YS strobes (Sony adapter required). Ergonomic, mechanical controls, including levers, pushbuttons, and dials, provide access to virtually all camera functions, while dual side grips offer balance and handling, and give you attachment points for lighting arms. Built for durability, the housing is constructed from precision-machined aluminum that has been anodized for resistance to corrosion. The housing is designed with a buoyancy pocket that reduces its weight underwater or can accommodate a mobile battery charger for more shooting time. A built-in leak sensor alerts you immediately in the unlikely event of a breach in the waterproof seal. The MDX-A7III ships without a required lens port, and accepts a series of interchangeable ports for various lenses. The optional VF45 and VF180 viewfinders can be added on to enhance your view for better shot composition underwater.
