The L-Plate Set for Select Sony Alpha a7 Series Cameras from Really Right Stuff is a modular design composed of an Arca-type compatible base plate and L-component that facilitate easier, more stable switching between horizontal and vertical shooting orientations when working on top of a tripod.
The CNC machined 6061-T6 aluminum L-plate set maintains complete access to the battery door without obstructing the tilting LCD monitor of the camera. Plus, both parts can be separated slightly, and retightened with a hex key if more room is needed for your tethering or cable release.
The L-plate set has been type II black anodized, which makes it resistant to scuffs and scratches. Furthermore, the base plate has laser-engraved center marks on the back to align it on a tripod head.
