The Cavision 64-67mm Follow Focus Gear Ring clamps around a lens' focus ring to allow use of an add-on follow focus system. This gear ring is specifically designed for lenses sized between 64-67mm.
Note! For DSLR lenses, focus barrel size does not correspond to filter thread size; please measure the diameter (or circumference divided by 3.14) of the lens' focus barrel to determine the correct gear ring.
- Can be clamped onto the focus ring of video, film or DSLR lenses, allowing for the use of a follow focus.
- All rings compatible with standard Fujinon (mod 0.6) gear type.
