This must be the 4345th reviewer of this digicam that renarks on the lack of 720p video in this cam, and we all know it's Sony's fault. Bad Sony!:   "Autofocus is pretty good though again not blazingly fast. It's a little quicker at the wide end of the range (under 0.5s) than it is at the telephoto end (under 1s). Again, OK by digicam standards, slow by DSLR standards. There is a very effective and pretty bright AF assist light (which is purple/blue rather then the typical red) which comes into operation when the G11 has trouble focusing. AF seems accurate. I didn't see any problems when using AF for lens resolution testing. The G11 has a manual focus mode in which the center of the LCD screen shows a magnified image. There's also a distance scale displayed in manual focus mode."   Link   Link to sensor specs @ Sony (PDF file)
