These right-angle quick release "L-brackets" fit to the base of your camera or its accessory battery pack so you can quickly release, turn, and remount your camera for either a horizontal or vertical shot. No more flipping your tripod head on its side or upsetting your shooting position. These plates work especially well when you're using shorter macro, wide-angle, and tilt-shift lenses. PLEASE NOTE: all L-brackets must be used in conjunction with Arca style quick release platforms.
