The U-B 100 Underwater Housing from Ewa-Marine is a waterproof enclosure enabling you to shoot beneath the surface with your pro DSLR, such as the Canon EOS 1D X or 5D Mark III, or the Nikon D4 or D3. It will also accommodate a different camera of similar size. The U-B 100 is a modified version of Ewa's U-B housing, with a wider lens port to allow for the use of lenses with larger diameters. It has a depth rating of 65.6' and a corrosion-resistant clamping rail seal.

The housing includes Ewa's Tripod Connector with Mounting Plate and their Cable Exit. The tripod mount has an anodized aluminum plate with both a 1/4"-20 and a 3/8"-16 screw threads and a quick-release head. The cable exit allows you to run up to 4 cables out of the housing and still safely dive. Each cable can have a maximum diameter of 4 mm.

Easy access to virtually all camera controls is provided right through the thin, flexible, double-laminated PVC housing body, which is clear to allow you to monitor the watertight seal and maintain a full view of the camera. The integrated, optically neutral flat glass port accommodates lenses with internal focus mechanisms only and is especially designed for wide-angle lenses. The supplied CA-77 adapter is compatible with lenses that have 77mm filter thread diameters, and fixes the front element of the camera's lens to the interior of the port to hold it in place. The optional CA-82 adapter enables the use of lenses with 82mm threads, and optional step-up or step-down rings can be screwed on to accommodate lenses with different thread sizes.

The U-B 100 is supplied in a handy yellow carrying case with a waterproof interior. Also provided are an initial supply of CD5 drying agent to absorb moisture/condensation and enough foam padding to take up any empty space when shooting above water. Below the surface, the water pressure will compress the housing, eliminating excess space. However, you should still keep the foam padding inside and blow additional air into the housing via the valve at the rear, to ensure that there is enough interior pressure to withstand the exterior water pressure.
Waterproofing
Features a depth rating of 65.6'. Corrosion-resistant clamping rails fit together and are tightened via 3 screw knobs for a secure watertight seal.
Control Access and Handling
Easy access to virtually all camera controls, including auto focus, is provided right through the thin, flexible housing body. The optional BF1 lead weight reduces the buoyancy of the housing to make it easier to reach lower depths.
Construction Details
Has a double-laminated PVC body, which is clear to allow you to monitor the watertight seal and maintain a full view of the camera.
Lens Port
Built-in, optically neutral, flat glass port accommodates most wide-angle lenses, including those with focal lengths of 16mm (35mm equivalent). All lenses used in the port must have an internal focusing mechanism. The supplied CA-77 adapter is compatible with lenses that have 77mm filter thread diameters, and fixes the front element of the camera's lens to the interior of the port to hold it in place. The optional CA-82 adapter enables the use of lenses with 82mm threads, and optional step-up or step-down rings can be screwed on to accommodate lenses with different thread sizes.
Flash Use
You can use the camera's built-in flash in the housing, either by itself or as a trigger for an optional, external wireless slave flash, which will provide better illumination.
Bundled Accessories
Includes Ewa's Tripod Connector with Mounting Plate and their Cable Exit. Tripod mount has anodized aluminum plate with both a 1/4"-20 and 3/8"-16 screw threads and quick-release head. Cable exit allows you to run up to 4 cables out of housing and still safely dive. Each cable can have max diameter of 4 mm. Housing supplied in handy yellow carrying case with waterproof interior. Also provided are initial supply of CD5 drying agent to absorb moisture/condensation and enough foam padding to take up any empty space when shooting above water. Below surface, water pressure will compress housing, eliminating excess space. However, you should still keep foam padding inside and blow additional air into housing via valve at the rear, to ensure that there is enough interior pressure to withstand exterior water pressure.
Compatible Cameras
Pro DSLRs, including Canon 5D Mark III and EOS 1D X, and Nikon D4 and D3, as well as other cameras of the same or slightly smaller size, such as Canon 5D Mark II and Nikon D300 and D800.
