Surely enough, it doesn't have the robust build, comfortable hand-grip, weather sealing, dual control wheels, large viewfinder, 8fps burst mode or 19-point auto focus module of the EOS 7D - but then a Rebel probably never will.

Overall build quality is very good too, with much of the body constructed from magnesium alloy.

The camera also delivers the best video capture quality I've seen in a sub-$1,000 dSLR-subject to the inescapable limitations the technology, like unusable autofocus-with good exposure, sharpness, minimal artifacts, and excellent audio.

While the EOS 550D can shoot at 3.7 frames per second in Continuous Shooting Mode, it's restricted to 34 JPEG images, or six RAW files – so sports and action photographers might want to look elsewhere.
