youmagine

This is a custom set of lens-gears for use with a follow focus. Compatible with standard industry follow focus systems, these lens-gears offer a convenient alternative to buying expensive units in stores. Pitch: 0.8 Tooth: 97 Each gear has the same outer diameter but different inner diameters, allowing for seamless transitions between lenses without needing to adjust the follow focus. All gears feature their nominal inner diameter labeled clearly on them in large letters. Example lens-sizes for several DSLR lenses are listed below: Name .......................
