(the camera shown on the picture is not included)

The U-BXP 100 housing is a special version of the U-BXP .

It has a wider frontglass and allows in combination with the C-A 77 adapter (supplied with the housing) and C-A 82 (available as an accessory from your dealer) adapter the use of lenses with a filter thread of 77 and 82mm.
This means you can use your professional digital SLR camera like the Canon EOS 1D, 1Ds Series as well as the Nikon D1, D2H, D2X, D200 and similar cameras, with most of the professional wideangellenses currently on the market.

This enables you to use wideangel lenses with a focallength of 16mm (full format chip)without problems. SLR cameras which have a smaller chip can even use the 10mm wideangellenses.

please note: all lenses used with this housing must have a internal focus.

Lenses with a smaller filterdiameter can also be used in this housing as long as they have internal focus. You just need the right step-up ring.

The autofocus adapter (AV110) is not included in delivery as it is not needed for this housing.

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 utilised.

The U-BXP100 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.
