The Ewa-Marine U-BF Housing was specially designed for large digital SLRs such as the Canon EOS 1D, the Nikon D3, or Sony Alpha 900, with small lenses that have a filter thread up to 72mm. The housing will also accommodate smaller SLR cameras with a battery pack. It is manufactured from double laminated PVC and has an optical glass port. A pair of non-corrosive, seawater resistant clamping rails fit together to keep your camera safe and dry down to 33' (10m). The U-BF comes with a glove integrated into the housing, so your left hand has access to the lens. All camera controls are accessed through the PVC.

This housing is ideal for working in or near water close to the surface. The housing accommodates autofocus SLR cameras without shoe-mounted strobes, with a maximum dimension of 9 x 9 x 5" (228.6 x 228.6 x 127mm), with lenses that have a maximum filter thread of 72mm. Keep in mind only internal focus lenses can be used with this housing. The housing is shipped with an Ewa-Marine CAF adapter system set to connect the camera's lens to the port. Adapters with a filter thread of 49, 52, 58 and 62mm are included. 67mm or 72mm Ewa-Marine CAF adapters are available.
