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 camera also delivers the best video capture quality I've seen in a sub-$1,000 dSLR-subject to the inescapable limitations the technology, like unusable autofocus-with good exposure, sharpness, minimal artifacts, and excellent audio.
