Q: 9. Can the hard stops be removed for lens that already have hard stops and require more than one full rotation of the control?

A: Alan I have a lens with hard stops. The purpose of the follow focus is to create hard stops inside the range of the hard stops on the lens. If you wish to use the lens hard stops simply push the hard stop arrow on the FF all the way back to disengage it. you can also loosen the adjustable screws so that they rest at the bottom of the disk and don't interfere with anything else.
