Ewa- Marine U-B-100 (U_B_100, U/B/100, U B 100) Underwater Housing for SLRs w/ 82mm Filter Thread Lenses

The Ewa-Marine U-B 100 housing is specially designed to fit bulky, digital SLR cameras such as the Canon 1Ds, Nikon D3, D300 and other cameras around the same size. Smaller SLR cameras can still be used in the housing. The housing is manufactured from double-laminated PVC and has an optical glass port.

The lens port is wide in order to accommodate lenses with a large diameter. Use the included C-A 77 adapter for lenses with a 77mm filter thread or the C-A 82 adapter for lenses with an 82mm filter thread. All lenses used with this housing must have internal focus.

erfect for snorkeling, diving or for use in sandy, dusty, humid or foul weather conditions. This housing will give your camera the best possible protection while being fully operable. The housing is perfect for canoeists and other outdoor photographers that want to take pictures of wildlife while in or near the water.

If the optional BF1 lead weight is inserted, underneath the camera, it becomes even easier to reach the maximum depth of 60'. The auto focus of the camera continues to function perfectly. As you descend, the air is pressed into the camera. Due to this, the pressure inside the housing will remain the same as the surrounding water pressure (this is the reason why ewa-marine housings are so safe to use: implosions are impossible). Due to this, you must start the dive with a suitable amount of air inside the housing. The foam pads supplied with the housing are part of this air "reservoir" and additional air should also be blown into the housing, via the valve at the rear, to ensure that the maximum volume is being utilized.

The housing has a pair of non-corrosive and seawater-resistant clamping rails which fit together for sealing. They tighten by means of screw knobs. This housing accommodates a maximum 82mm lens filter thread. The lens could be as long as 7.87" (200mm).
