There is an improvement in its inner structure to reach a high level in this field, the Dampened gearbox, which permits much less backlash(even zero backlashes), even better than most follow focus on the market.
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.
Furthermore, the gear wheel on it can be detached and installed on both sides, which makes it suitable for both left-hand and right-hand photographers. The connection mount to the gear wheel is not only the newest version but also the last upgrade version.
The white mark ring is made of the magnet material. It can be detached or attached easily and quickly from the follow focus. You can also buy an additional mark ring.
The special part of this follow focus is it can use different size gears. It can work with 3 different size gear to meet your different need with various lens: M0.8-38T M0.8-43T M0.8-65T gear
