The housing is compatible with the a7 Mark IV and the new a7R Mark V. Originally
designed for the a7 IV, a upgrade kit could be added to allow compatibility with the a7R V. Camera mount and control modifications are included in the box.

The housing features an ABS-PC blend body and transparent back, Dry Lock (DL) port system, ergonomically designed levers and hard-anodized aluminum buttons, and an M16 port for attaching accessories such as an external monitor/recorder.
There’s out-of-the-box manual triggering of strobes by Ikelite, Sea&Sea, Inon, and Retra, as well as TTL exposure with Ikelite DS-series strobes when adding the optional DL2 DS Link TTL converter.
