Reviews Word on the street

Rebel T3  vs EOS 7D

Its excellent EVF, versatile and intuitive live view and AF system, and its solid, reassuringly well thought-out operational ergonomics are all better reasons to buy this camera.

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.

With an 18-megapixel APS-C CMOS sensor and a price tag of £1,500 body-only the 7D hits the mark perfectly.

It's also built incredibly well and the video mode, while not perfect, is better than any other HD-DSLR we've seen, thanks to its excellent quality, full manual control and 24p frame rate.
