The FocusONE v2 Follow Focus Unit from edelkrone is a single rod-based follow focus unit that mounts the marking disk between the handwheel and the drive gear, which provides extremely precise focus marks. The v2 model updates the unit with A/B hard stops for even more precise focus movements. The unit features an industry-standard 0.8 MOD drive gear, and the gearbox has an adjustment screw so you can set the tension and play to fit your comfort level. An industry-standard whip/crank socket allows you to use an available speed crank or focus whip if you desire. The unit can also adjust to accommodate pulling focus with virtually any diameter lens that you can use with a 15mm or 19mm rod. The unit can easily tilt and adjust with your camera setup, and it can be mounted on either side of the lens. The marking disk faces the operator, giving additional confirmation to the operator that the lens is at the proper mark, and it is also lined up precisely with the focus ring for an accurate focus pull. Adjusting the marking disk is simple to do even without a marker by setting the lens where you want it, rotating the disk to the index mark you wish, and then you can change focus back to the mark you set. The marker disk is made from plastic, and you can place additional index marks on it with available temporary markers of your choice.
