The BA72 L-Plate Set for Sony Alpha a7 II and a7r II Cameras from Really Right Stuff is a modular design composed of a Base Plate and an L-Component. Both parts create an L-Plate, which can be changed while on top of a tripod, from a vertical to a horizontal position, without sacrificing your center of axis. The Arca-type compatible dovetail plate adds quick release functionality to the camera, and anti-twist flanges and the and 1/4"-20 mounting socket keep the camera body in place.
The L-Plate maintains complete access to the battery door and the camera's ports. Both parts can be separated slightly, if more room is needed for your tethering or cable release, and retightened with the included hex key. Furthermore, there is no obstruction to the movement of the LCD monitor on the camera, which allows at least 50% downward tilting. In addition, a boss has been machined into the side of the plate, so an accessory hand or shoulder strap can fit.
Type II black anodizing has been applied to the CNC machined 6061-T6 aluminum. The anodizing has given the L-Plate a smooth surface, which is resistant to scuffs, scratches, and corrosion. Furthermore, the L-Plate has laser engraved center marks on the back of each axis for alignment on a head.
