The Triad RF-15 Follow Focus is a gearless device that attaches to a DSLR shoulder-mount or tripod rig by way of its standard 15mm rod mounts. The RF-15 uses a horizontal adjustment to make contact with your wide or mid-range telephoto lens. Instead of purchasing and installing a separate gear ring for each lens in your kit, simply adjust the horizontal element of the RF-15 to match the diameter of your lens. The friction between the follow focus and the lens's focus ring is sufficient to enable the operator to pull accurate focus smoothly. The wheel that you operate is markable so that you can repeat focus-pulling moves.
