The Ewa-Marine U-BFZ Underwater Housing for DSLR Cameras is a waterproof case enabling you to shoot beneath the water's surface with your digital SLR camera and lens. It accepts a variety of cameras, such as the Canon EOS 1D, the Nikon D3, the Sony Alpha 900 or the Leica S, and will fit camera / lens combinations up to 9" (23 cm) in length. The housing's integrated, optically neutral flat glass lens port will accommodate lenses with up to a 72mm filter thread. All lenses must have internal focusing. The housing has a depth rating of 32.8' (10 m).

The U-BFZ provides access to all camera functions, which are operable through the housing. In addition to the little finger insert that lets you operate the shutter release with your right forefinger, the U-BFZ features an integrated glove designed for left-handed use. It allows you to cradle the camera and lens the same way you would when using the camera without the housing. Having your hand on the lens enables you to operate the camera and lens manually.

The housing is constructed from clear double laminated PVC. It comes with an Ewa-Marine CAF adapter system set for connecting the camera's lens to the inside of the lens port. Adapters with a filter thread of 52, 55, 58 and 62mm are included. You may also purchase optional 67mm or 72mm adapters.

Two clamping rails anodized for corrosion resistance fit together to form a watertight seal; you can tighten them via three screw knobs. The included water-resistant yellow carry-case is not meant for submersion, but will protect your gear against splashes.
