The APOS2672 Left Side Plate with Cable Lock for Sigma fp Camera from SmallRig locks to the body's 1/4"-20 socket, and an anti-twist locating pin prevents the camera from moving while mounted to the plate. With the plate attached to the camera body, it provides two 1/4"-20 and one 3/8"-16 socket for accessory attachments such as a camera grip.
