Good shoulder plate. Note: if the bottom of your camera is not completely flush, careful not to overtighten the plate to the bottom of it. If it's too tight, the plate could flex, which makes it difficult to smoothly slide/mount to the shoulder piece.

From SmallRig:
"SmallRig Sony VCT-14 Shoulder Plate 1954 is compatible with Sony VCT-14 tripod adapter plates. It could be attached and detached fast, able to support heavy device and keen to get a balance when the camera is mounted on it. It features a Manfrotto 501 quick release plate, and shooting on the shoulder, in the hands and on the tripods could be switched swiftly.

Part of the baseplate extends out beyond the 15mm LWS rod adapter in the front. With rod adapter set back, additional space in the front is achieved to mount follow focus. It enables to position the camera backwards to some degree on the plate, so as to get the balance of your rig directly over your shoulder. The rod adapter is vertically adjustable by 23mm to fit different types of cameras, like FS7/FS7II/FS5/Ursa Mini/Canon C100. What’s more, it is equipped with a 15mm LWS rod adapter on the rear side."
