• VariZoom VZ-EFC Remote Electronic Focus Control for Canon and Fujinon Professional Lenses
What it's for... The VZ-EFC provides remote focus control for Canon or Fujinon professional lenses being used on jibs, cranes or other remote applications.
How it works... The EFC features a battery-powered control unit that connects to a servo focus bracket that drives the focus ring on the lens. Operate in Manual Mode for full-range focus adjustment or in Programmable Mode for up to 4 preset focal points.
Where it connects... Clamp the control unit to your jib weight bar and attach the servo focus bracket to your lens using the standard thread mount.
