Originally posted by manishved I would add decent video capability as a basic requirement and AF during video as a big plus.
Sony's cameras do have decent auto focus, but what Nikon put in their cameras is not very good at all. Better off by far manual focusing. It just doesn't search back and forth as much and there isn't the noise of the camera focusing added into the audio.
Pentax could have allowed their live view focus to be usable during videoing, but they didn't feel it was adequate (I agree); however, that is exactly what Nikon did use.
