The Arca-Type/Manfrotto RC2 Quick Release Plate from SmallRig is compatible with both quick release systems. Therefore, if you own both systems, then it's convenient to use this plate. The aluminum plate tightens to the camera via its 1/4"-20 threaded mount by turning the integrated D-ring or by using the included hex spanner. With the plate's rubberized top, it prevents the plate from moving while attached to the camera body, and in each corner of the plate are located lanyard holes to attach Rapid Link Connector straps.
