The Kirk BL-5DG is an ultra-compact and lightweight L-bracket that is custom designed to snugly fit a Canon 5D with BG-E4 camera combination. Machined from one single piece of 6061T6 industrial strength aluminum, it provides full access to all switches, sockets and the battery drawer. This design allows you to release, turn and remount your camera in mere seconds, when switching from horizontal to vertical orientation and back. It is especially ideal for use with shorter macro, wide-angle and tilt-shift lenses.
