The Sony MPK-HSR1 Waterproof Housing makes it possible to take your Sony RX0 ultra-compact camera underwater. With this aluminum-alloy housing, the camera can function smoothly from a depth of 330 ft water. It also protects the RX0 from impacts and shocks, besides preventing it from getting crushed. Further, this housing does not get in the way of accessing the various control buttons on the camera. It also has an accessory shoe on the top for mounting an onboard light. The front thread of the housing can take 55mm filters.
