Professional friction driver for OConnor follow focus systems. Enables precise focus control on lenses without geared barrels or standard 0.8 mod teeth.
This seamless clamp on gear ring clamps securely around the focus barrel of your lens by tightening one little screw (allen key is included). Once tightened, the slit in the ring disappears and makes the ring seamless. The tooth size is M0,8.
