Sterling Zumbrunn has published a comprehensive review of the Canon T2i on Backscatter, including a review of the current housing choices. He identifies the camera as being the “most exciting SLR offered from Canon this year,” and the testing was carried out on it by a total of eight individuals in a variety of environments worlwide.
To summarize his findings: The camera gives exceptional performance and amazing value. Positioned as an entry-level SLR, it’s performance and feature set are anything but entry-level, and it provides an ideal step-up from a compact camera. It’s small size and weight make it also very suitable for traveling or blue water divers, at the expense of some compromises in “performance, ergonomics and construction,” when compared against the Canon 7D.
