The Sigma TS-111 Tripod Socket for 100-400mm f/5-6.3 DG DN OS Contemporary Lens is a single-locking knob collar that can be used as a spare or as a replacement part that originally came with the lens. Once the collar is on, it enables the lens and camera to turn on axis in a vertical or horizontal position. In addition, the dovetail foot on the tripod socket is compatible with most Arca-type clamps.
