As with Live View, continuous phase-detection AF is possible whilst shooting movies on the A37, a distinct advantage over most DSLR cameras and fast enough to rival Compact System Cameras like the Panasonic Lumix GH series.

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.
