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 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 the use of large floats is typically not needed.
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.
* Sony original adapter "ADP - MAA" is required separately for connecting camera and optical converter.
