What is a Follow Focus?

From http://en.wikipedia.org/wiki/Follow_focus
A follow focus is a focus control mechanism used in filmmaking with film cameras and in television production with professional video cameras. It is ergonomic rather than strictly necessary; in other words it does not contribute to the basic functionality of a camera but instead allows the operator to be more efficient and precise. It is usually operated by a focus puller (often called the 1st assistant camera, or 1st AC) but some camera operators prefer to pull their own focus (the act of changing focus is called "pulling" or "racking" focus).

A follow focus is usually a compulsory piece of equipment for professional filmmaking, although those with low/no budgets or cameras not equipped with detachable manual lenses will have to do with autofocus systems or turning a lens ring by hand.

Question: Hey, this is a great little FF, but will it mount onto Canon's 50mm EF 1.8 ii. It has a thin tapered focus ring, with a 52 mm diameter.

Answer: FocusShifter works for your lens (Canon-EF-50mm-f-1.8-II-Lens). The FocusShifter belt is made of neoprene and will hold well on the focus ring if it is clean (no oily finger prints etc.) Occasionally, a thin rubber band inserted between the focus ring and the FocusShifter belt will improve the holding ability.
