The housing can be used on small boats, in the surf, while swimming, snorkeling or diving. It's easy to operate as the camera as its various components and buttons can be operated through the PVC.
The U-BXP is specially designed to fit the bulky, professional digital SLR cameras like the EOS 1D, 1Ds series, or the Nikon D1, H2H, D2X, D200 and similar cameras. Smaller SLR cameras then the mentioned above can still be used in the housing.
Please note: In this housing you can only use lenses till a maximum filter thread diameter of 72mm. If you are using lenses with a 77mm or a 82mm filterthread, then you must use the U-BXP100 housing.
With this housing, a whole new world of applications opens up for your professional digital SLR camera: Inside the housing you can now take the camera safely canoeing, snorkeling or even diving, up to a depth of 50 m / 150 ft.
If the optional BF1 lead weight is inserted into the housing, underneath the camera, it becomes even easier to reach the maximum depth. Experienced photographers have confirmed, that the auto focus and flash both continue 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, we have to 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 potential volume is being utilized.
The U-BXP housing is manufactured from double laminated PVC and has an integrated, optically neutral flat glass port. The external flash that is commonly used on SLR cameras fits into the specially designed section on the top of the housing.
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. It is supplied in a handy yellow carry-case which has a water-proof interior and zippered side-pocket.
