ewa-marine U-B

The U-B is a practical, "all-round" housing that is primarily intended the be used while swimming, snorkeling and other, general water sports. While it can also be used for scuba diving, for lack of a strong, external strobe, and because the camera's small, built in flash is to close to the lens, resulting in small, suspended particles in the water showing as  "snowflakes" in the picture, i.e. can not be used in most applications, the U-B is limited to 20m / 60ft. A depth where you also can still take pictures with ambient, natural light. Since underwater photography generally requires the use of wide angle or macro lenses and thus shorter lenses, the lens tubes on the housing is kept rather short.
The U-B is also our most cost-effective dSLR underwater housing in the ewa-marine SLR range.

Depending on your application but the following products offer a better solution:

• U-B100: For camera lens combinations where the lens diameter is too large for the U-B. i.e. filter thread 72mm, 77mm or 82mm
• U BXP: SLR with top mounted strobe and up to to 50m / 150ft dive depth. Primarily for scuba diving.
• U BXP100: Similar as the U-BXP but with camera lens combinations where the lens diameter is too large for the standard unit. i.e. filter thread 72mm, 77mm or 82mm
• U-BZ100: For outdoor photography while canoeing or kayaking with long zoom lenses

Designed specifically for professional, digital dSLR cameras, the ewa-marine U-B underwater housing is manufactured from our special, double laminated PVC and has an integrated, optically neutral flat glass as a front port. With this housing you will receive a set of adapters that fit the  filter threads of the most popular lenses on the market today. By means of this adapter the camera is then docked into the housings front port, ensuring that the lens remains parallel and centered behind the front of the lens. Just as if it were a clear, neutral optical filter.

To fix the right hand near the shutter release, the housing has an adjustable wrist strap and a "Finger" to position the index finger right on the trigger.

Our SLR housings are sold with a foam padding that fits underneath the camera, inside the housing. This sponge has to be removed if you want to use your camera with a battery grip, or to make space for the tripod connector that is available as an optional extra. (Please keep in mind that, as a result, cameras like the Nikon D4 or Canon 1DX, that basically include a fixed "battery grip" as part of their design, can not be used inside the housing that has been fitted with a tripod connector.)

It has a pair of non-corrosive and seawater resistant clamping rails which fit together for perfect sealing.They tighten by means of three screw knobs. There is also the practical, adjustable carry strap on the clamping rail.

It is supplied in a handy yellow storage and carrying case.

Actually, it's not in a box at all. We sell this unit in a handy, yellow, nylon carry bag. This bag is ideal to store and transport your ewa-marine housing, it also helps reduce unnecessary packaging-waste and as such is part of our amain to help the environment.

• CA-Adapters (for 52mm, 55mm, 58mm and 62mm filter thread*)
