As with Live View, continuous phase-detection AF is possible whilst shooting movies on the A57, a distinct advantage over most DSLR cameras and fast enough to rival Compact System Cameras like the Panasonic Lumix GH series.

The versatile swivelling LCD screen encourages creativity when it comes to framing stills and videos, the EVF is great and image quality is very pleasing - particularly when it comes to noise control.
