The housing can be used on small boats, in the surf, while swimming, snorkeling or diving. It's easy to operate the camera as its various components and buttons can be operated through the PVC.
The U-A is designed to fit almost all common SLR cameras on the market today, irrespective of the manufacturer or model. With this housing, a whole new world of applications opens up for your standard SLR camera: inside the housing you can now take the camera safely canoeing, snorkeling or even diving, up to a depth of 20 m / 60 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, the dive must be started 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.
Designed specifically for 35mm SLR cameras, the U-A housing is manufactured from double laminated PVC and has an integrated, optically neutral flat glass port. The flip-up, internal flash, that can be found on some models will fit into the specially designed section on the top of the housing, allowing its use above and under water.
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.
The package includes a yellow carry-case which has a water-proof interior and zippered side-pocket, a manual for ewa-marine SLR-photo housings, an initial supply of CD5, a specially profiled foam padding, and an AV110 autofocus adapter.
