Loading... Please wait...The Genus Superior Follow Focus System for DSLR Cameras allows photographers to easily change pitch gears using a sliding bracket. The unit also features a clamp-on quick release bar which allows it to be detached easily without dismantling any other part of the rig. A G-PG08 0.8 pitch gear and G-FG flexible lens gear ring are included with the system, and can be interchanged with other Genus pitch gears. It can also be flipped to allow reverse rotation, and has a reusable beveled marking disc allowing you to mark your preference on the disc.
