The Phottix BG-60D Premium Series Vertical Grip/Battery Holder for Canon 60D digital cameras is a grip that can hold two LP-E6 or six AA size batteries to offer double-length shooting time. It is also equipped with a vertical-grip shutter button, dial, AElock/FE lock button, and AF point selection button to make shooting with the camera in a vertical position just as comfortable as shooting horizontally.
