The Isotta Sony Alpha 7S III Underwater Housing allows you to capitalise on the full potential of the Sony Alpha 7S III Full Frame Mirrorless Camera and to capture amazing pictures underwater. It is an easy to use, highly professional product that has been created through techniques and innovations gained from years of experience.

Easy access to all key/main Sony Alpha 7S III camera controls by means of clearly labelled laser-engraved long-lasting buttons. The back door has a large window for a fine camera display view and it is entirely detached from the front body to make for easier camera fitting. The housing stands with great stability due to sturdy and wide rubber feet located on the bottom.

One Hand Open/Close
It's very easy to open and close Isotta Sony a7S III camera housing, without effort by the user thanks to the upper helicoid and the bottom centred pins; the camera is placed easily into the housing on a sliding tray that keeps the camera robustly in place.

Ports and Extension Ring
A series of ports and extension rings are available. The removable port is fitted thanks to markers and a bayonet 120 mm connection to the Isotta Sony a7S III housing. The interchangeable port bodies and extensions rings allow the use of most of the lenses on the market for maximum versatility and performance.

Two fibre optic connections allow the use of external strobe through the manual trigger. The housing features two M16 holes and one M24 hole for the installation of accessories, e.g. syncro cords, vacuum valves, monitors.

Construction and Safety
Only the best materials are used to manufacture Isotta housings such as anodised aluminium, which is anticorodal and thermo-coated, and stainless steel. A long-lasting product that requires easy and simple maintenance by the user. So small and so rich in technology! Dual high precision and quality O-ring seals protect and ensure a perfect and secure watertight for all movable and/or removable parts. A red alarm for humidity/water inside the housing is powered by a battery replaceable by the user. The working depth is 100 metres. Different accessories can be fitted directly on the handles or by means of an M8 upper threaded hole, using the Isotta top handle or via the M6 and M8 threaded holes on the bottom.
