For users moving up from compact cameras, the 650D offers a very significant increase in image quality and a comfortable to hold camera wrapped in an interface that accommodates both touchscreen and external control operation.

ISO performance is pretty good on the whole and while some noise does begin to show itself as low as ISO 400 images retain their integrity right up until ISO 12,800.

The control layout on the back remains essentially unchanged, but Canon tweaked the design on the menu and info buttons for the better; they're slighly easier to feel now.
