Reviews Word on the street

Rebel T3  vs T1i 

At 720p the footage is not quite as detailed as the 1080p output of some of the competitors but motion is smooth and there are no visible artifacts.
Rebel T3

The small body, large buttons and intuitive external controls, Creative Auto mode and on-screen Feature Guide make the EOS 1100d more appealing to owners of compacts looking to upgrade to a DSLR, but we'd also have liked to see an integrated cleaning system and the Scene Intelligent Auto mode included too, both features which would have made this camera even more beginner-friendly.
Rebel T3

The image quality is quite printable at 1600 ISO, which is about what you need for good indoor no-flash photography.
