The Laowa Tripod Collar for 100mm f/2.8 2x Ultra Macro APO from Venus Optics is designed for this lens, and it gives you the option of mounting the lens to a tripod, which provides a steadier shot. The collar attaches to the rear barrel of the lens, and the locking knob located on the left of the ring allows you to rotate the lens from a horizontal to a vertical orientation.
