Our testing team was one of the first to get their hands on the new Canon EOS 650D. They've posted their full, scientific Canon 650D review over on our sister site TechRadar . So go there for all your image quality analysis, noise charts and more.
We found the articulated touchscreen responsive and easy to use; It enables quick settings adjustments and fast shooting from awkward angles, but if you don't want to use it you still have all the button controls you would expect on a DSLR
Although it has Canon's rating system that enables you to score images with up to five stars; there's no dedicated rating button; so it's not quite as quick to use as with the Canon 5D Mark III.
