The U-BXP 100 is a special version of the ewa-marine U-BXP underwater camera housing.

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 D2X, D3, D300S, D700 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.
