This Follow Focus / Riser /15mm Rod Kit from SHAPE combines into one bundle all the components needed for you to start pulling focus on your DSLR or camcorder. Included are the Shape follow focus, a pair of 15mm rods, and a camera riser. The follow focus features both friction and geared lens interfaces, a removable marking disk, and a clamp-on 15mm rod base. A single lever locks the half-moon shaped base onto the rods, eliminating the need to slide other accessories off in order to mount the follow focus. Another lever enables you to adjust and lock the follow focus horizontally to fit different lens diameters. The versatile SHAPE follow focus can be used on either side of the lens.
