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 FOTGA DP500IIS follow focus is upgraded based on the previous DP500II version follow focus. It is consisting of a dampened gearbox. There is a button downside can adjust the tension of the gearbox to reach 2 dampen level. Besides, the inner structure of DP500IIS follow focus is improved, which ensure much more accurate operation for your work.

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.

Quick-release version, easily attach and detach.

Further more, the gear wheel on it can be detached and installed 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 easily on matel. You can also buy additional mark ring.

Scale mark part of this follow focus can be rotated, which means when you put all follow focus rig on your shoulder or somewhere much high and you can not see the scale mark, you can adjust the scale mark to the point where your sight can reach. This would be very helpful during working.
