The review.
Quote:
"The 600D's APS-C format sensor is smaller than the full-frame sensor inside its stablemate the 5D Mark II, but larger than the Four Thirds format sensor of a camera like the recently reviewed Panasonic Lumix DMC-GH2, and far larger than the sensors in any compact camera. As such, although the 600D doesn't give you quite the same control over depth of field as you'd expect from a full-frame camera, the creative possibilities of video with the 600D are much greater than they might be with a compact, where control over exposure and depth of field is often minimal and occasionally nonexistent."
