Nauticam has release a few renderings of their upcoming underwater housing for the Canon Rebel T2i / 550D digital SLR.

Notable changes from their prior housings include an ISO button / piano key located near the shutter release, and a standardized play lever by the left handle (where it is also located in their Nikon housings). The Rebel series SLRs do not have separate dials for aperture and shutter speed, but the addition of ergonomic access to the ISO button means that in future housings, all three exposure controls will be accessible without removing one’s hands from the handles.
