The Dedicated Power Zoom Shoe-Mount is an autofocus TTL power zoom lens for digital Sony/Minolta SLR cameras. Its auto-zoom flash head senses the focal length of the camera's lens and adjusts accordingly. There is a built-in slave mode and it can tilt (0°-90°) and swivel (0°-270°) for complete lighting control and shadow-free flash photography. Additional features include red-eye reduction, automatic shutter speed setting, front and rear curtain synchronization, and a 24mm-85mm zoom range.
