Reviews Word on the street

Rebel T5i  vs EOS 550D 

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.
EOS 550D

While a 13x19 print of an ISO 6400 photo wasn't quite as clean or sharp as I would have liked, it doesn't look that bad.
Rebel T5i

We found that the vari-angle screen provides a good, clear view with lots of detail visible even in quite bright light, making it very useful when composing images at ground level or above head-height.
