The Custom L-Bracket for Sony a7 III, a7R III and a9 from Sunwayfoto is a solid single-piece design that is CNC machined from T6061 aluminum with a Type-III anodized finish for durability. The Arca-type compatible L-bracket can mount in both a vertical or horizontal orientation. Also, on the bottom of each axis are located dual safety stops as a precaution against the L-bracket from sliding out if the quick release clamp is partially opened by accident.
The camera mounts to the bracket via a 1/4"-20 male threaded screw, and the anti-twist lip on the plate prevents and minimizes any movement between the camera and the bracket. The camera's ports are completely accessible, but the 1/4"-20 mounting screw can loosen and readjust to allow the camera to slide apart to give more room for other cables. At the same time, the battery chamber and the tilting LCD screen are not blocked from being opened or to move freely about.
