The Kirk BL-6DG L-Bracket for Canon 6D with BG-E13 Battery Grip allows you to switch from portrait to landscape orientation and vice versa with your 6D efficiently, without the need to tilt your ball head and re-level the shot.
The bracket has channels on each side to fit popular Arca-type quick releases and a 1/4" camera screw. The BL-6DG maintains access to all important camera controls, such as the rubber side hatches, battery compartment, the remote switch even in vertical format and camera strap loop. The BL-6DG also features sensor centering lines specific to the 6D.
