the specs of Canon's latest mainstream DSLR, so let's skip past the new 18 megapixel CMOS sensor, SDXC memory card compatibility and high-res 3-inch LCD screen, and just focus on the one area where the Rebel T2i has a shot at matching the EOS 7D: 1080p video. Ron Risman of Cameratown has perched the two black-clad champs atop a tripod, installed identical (for the purposes of the test) lenses on them, and gone to town with testing the ISO performance of the two bodies. As he sees it, there's no perceptible difference between the two up to ISO 1600, though looking at his video test we're also hard pressed to distinguish any notable discrepancies at the maximum 6400 setting. Needless to say, the conclusion is that if you're just after the 7D's video performance with a smaller price tag, the Rebel T2i / 550D is the shooter for you. To make that decision as informed as possible, there's also a feature comparison list, so skip along to the source link to get informed.
