Reviews Word on the street

Rebel T2i  vs EOS 100D 

While video is probably the main application for the SL1’s improved Hybrid AF, I was pleasantly surprised by how well it worked when composing and shooting casual snapshots.
EOS 100D

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.
Rebel T2i

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.
