We'd heard inklings, but Canon's brand new Rebel T2i (also known as the EOS 550D outside the US) is newly official and oh-so-desirable. The camera takes quite a few features from Canon's EOS 7D, including an almost identical sensor, the selectable frame rates, and the stereo mic jack. There's also a new widescreen LCD and button layout to differentiate it from its T1i sibling -- which will stick around on the market to pick up the poorer Canon lovers among us. The shooter can capture 18.7 megapixel stills at 3.7 fps, with better, 7D-style light metering and an expanded ISO range
