The BL-A7R4 L-Bracket for Sony Alpha a7R IV from Kirk has a one-piece design, with anti-twist flanges that keep your camera from moving within the bracket. With its Arca-type dovetails, it enables you to mount the camera in a vertical or horizontal position onto a compatible head, and the black anodized 6061-T6 aluminum L-bracket has a slotted design for side port access. The bracket will not block the LCD monitor from tilting, it provides access to the battery door, and it has a hand strap loop machined on the right-hand side. The included hex wrench is used to tighten the L-bracket to the camera body, and it stores under the horizontal plate. A quick disconnect mounting socket is located on the bottom and sensor centering lines are on the back, so the camera can be aligned on a tripod head.
