The Ewa-Marine U-A Housing is an economical solution for using any autofocus SLR camera near or just under the water's surface, manufactured from double laminated PVC and with an optical glass port. It is rated for dives of up to 66 feet (20 m) depth; perfect for snorkeling, shallow diving, or generally sandy, dusty, and humidity weather conditions. The U-A gives your camera the best possible protection while being fully operable. When not in use, it is relatively light and takes up little space.

A pair of non-corrosive and seawater resistant clamping rails fit together for sealing, tightened by knurled screw knobs. The housing's internal glove allows easy access to camera controls. If your setup is too buoyant underwater, the optional BF1 lead weight can be affixed to the bottom of the housing.

The U-A housing accommodates an autofocus SLR camera without shoe-mounted flash, with the maximum dimensions being 6.7 x 5.3 x 6.7" (170 x 135 x 170mm) WxHxD with lens and a 72mm maximum lens filter thread. Adapters for 52, 55, 58 and 62mm filter threads are included.
