The Manfrotto follow focus features a zero backlash mechanism (no play between FF and lens movement) that allows the operator to pull focus precisely. It has hard stops that can be used to select a focus range between two points when needed. The gearbox direction is changeable, as well as the position of the follow focus once mounted on the rods, so it can be used with different lenses. The hand wheel has a standard square socket for attachment. The follow focus can be mounted on all 15mm rods and it is perfect in combination with Manfrotto Sympla 2.0.
