Developed exclusively for the 350 and 300 DSLR cameras, Quick AF Live View lets you frame pictures just like you would with any conventional compact digital camera. It lets you preview the image that you are about to take on the LCD of the DSLR without sacrificing auto-focusing speed common to other live-view systems.

The secret behind this is Sony’s proprietary Pentamirror Tilt Mechanism. Using a tilting mirror that directs light to a dedicated live view sensor behind the pentaprism, this enables fast TTL (through-the-lens) phase-detection auto-focusing, even during live view

Coupled with a variable-angle 2.7” LCD screen that tilts up and down to provide convenient high or low-position shooting, you can easily take pictures while holding the camera at arm’s length.
