Noise reduction through Anti motion-blur
SONY has a method of reducing noise which keeps the detail sharp and doesn't smear the image at high ISO. The camera selects the ISO and sometimes it uses ISO 6400 and produces good pictures. The camera makes six exposures rapidly and the computer combines the light from all of them. The variations in light (noise) are swamped out. For more info on this capability go to

This capability is so good it ought to be ann easier selection than going to the Scenes mode in menu.
