The standard, snap-on Follow-Focus works with 15×60 support rod systems. The position of the Follow-Focus in relation to the lens is adjustable and locks onto the rails with the red thumbscrew between the rail clamps. The side thumbscrew locks the Follow-Focus to the rails and allow for quick release and mounting.

The Petroff Follow-Focus is compact and precise without the unwanted play of competitively priced systems.
