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.

Sony's image processing is extremely good, and images shot though ISO 400 look very clean; depending upon content they can be usable and printed large (13x19) as high as ISO 6400, and ISO 12800 when scaled down.
