LuxGears are standard cinema pitched lens gears for use with a follow focus.  Each gear is precision molded in high-durometer silicone to create a fully functional compression fit on a lens’ focus barrel without the need for cumbersome buckle mechanisms that can get in the way.   The gears can be easily removed when  shooting stills.
