Grip sensor

The A100 had Eye-Start Autofocus, which initiated focusing when a sensor detected an object--ideally, your eye--behind the viewfinder. In the A700, Sony augments it with a grip sensor to minimize false starts. I still ended up turning the feature off: it doesn't seem to buy enough focusing speed to ameliorate the constant hum of the lens in motion.
