Canon carries over the control layout and user interface from the T2i, although it has moved the Display button to the top and replaced it with Info. Camera operation is straightforward. On the back there are direct-access controls for Live View/video recording, exposure compensation, white balance, autofocus method (single, AI focus and AI servo), drive mode, Picture Style, AE/AF lock and focus area (single-point manual or all-points auto). You can also change these settings, plus metering, flash, image quality, and a few others, via the typical Quick Control screen.
My one quibble here is that the buttons all feel a bit too flat.
