It's an obvious point - higher resolution sensors make higher demands on lenses - but it is one which is easily overlooked in the race to put higher and higher pixel counts into low-end and enthusiast DSLRs.

The Canon EOS 550D's maximum shutter speed is 30 seconds and there's a Bulb mode for even longer exposures, which is excellent news if you're seriously interested in night photography.

Shots at 1600 ISO are comparable with the results from the EOS 5D MkII, arguably the best high-ISO camera on the market, and even at 3200 ISO shots are perfectly usable, although quality does break down at the 6400 ISO maximum setting.

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.

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.
