DSLR 15 Meter FF A / B Hardline Follow Focus For Road Rail Cameras 5D2 5D3 7D 60D 600D
describe:
A follow follow is a focus control mechanism used in film and video cameras. it is working rather than strictly necessary; In other words it does not contribute to the basic function of a camera but rather allows the operator to be more efficient and accurate. It is usually operated by a puller focus but some camera operators prefer to pull their own focus.
The mechanism of action through a set of gears on the focus track is attached to the teeth on the focus ring of the lens. The gears feed to a wheel that, when turned by a puller focus, will spin the teeth and thus the ring into the lens.
