Sea & Sea MDX-A7III Housing for the Sony a7 III & a7R III Cameras

TTL shooting capability plus mobile Buoyancy Pocket for accessories such as Battery Chargers. Comfortably manipulate the next generation mirrorless camera and make the ultimate underwater image yours. Housing for the Sony mirrorless α7III / α7RIII.

Housing designed for ease of use and weight underwater

Compatible with all the DX (NX) ports series. Larger diameter lenses can be easily removed through the increased housing port diameter to enable battery exchange in camera body without removing the lens.

Sea&Sea engineers have designed a unique Buoyancy Pocket, which can also accommodate accessories such as a mobile battery charger, without compromising the overall size of the housing. The availability of an optional battery charger has addressed the battery life of the camera and allows shooting for extended periods without concern of camera power loss.

The internal space also contributes to the reduction of the weight underwater. Combined with the lightweight camera body, we realized a phenomenal underwater weight of 700 grams, eliminating the necessity to attach large floats.

Compatible with optical converter S1

Compatible with Sea&Sea "optical converter S1" which converts the strobe light emission signal of the camera to LED light and synchronizes with the Sea&Sea YS strobe. It is a high-performance converter that does not just emit simple light-emitting signals like other companies, but also performs TTL auto light control.
