A follow focus is a focus control mechanism used in film and video cameras. It is ergonomic rather than strictly necessary; in other words it does not contribute to the basic functionality of a camera but instead allows the operator to be more efficient and precise. It is usually operated by a focus puller but some camera operators prefer to pull their own focus . The mechanism works through a set of gears on the follow focus that are attached to teeth on the focus ring of the lens. These gears feed to a wheel which, when turned by a focus puller, will spin the teeth and thus the ring on the lens. This DP500 II follow focus is improved based on the previous DP500 version I follow focus.It is consisting of a improved dampened gearbox,which promise no backlash or less backlash(<0.5mm).There is a button downside can adjust the tension of of the gearbox to reach 2 dampen level. This improved Follow Focus Integrated with A/B Hard Stops which have easy begin/end setups for fast repeatable racking between two points, and make focusing lenses that have no hard stops (such as Canon EF lenses) much easier. Further more,the gear wheel on it can be detached and insalled in other side,which makes it suitable for both left-hand and right-hand photographer. The white mark ring is made of magnet material.It can be detached or attached very easliy and quickly on matel-made follow focus.You can also buy additional mark ring.
