The Preston Microforce V+F3 Zoom Control is used to control analog zoom motors mounted externally on the zoom lens, or the internal zoom motors of Panavision lenses. The Microforce VF+3 replaces the venerable 10 turn zoom sensitivity control with a virtually indestructible control knob and bright digital display.

The classic ergonomic design provides a rounded grip for comfortable all-day use and also offers a convenient attachment point for its mating Pan Arm adapter. Its housing, machined from solid aluminum alloy, protects the control from mechanical abuse and assures years of reliable operation. An integral camera run switch allows remote run/stop operation for both Film and Video cameras.

The V+F3 may also be used to provide the zoom function in conjunction with the FI+Z system as well as interface to professional Canon and Fujinon video lenses having 12 or 20 pin Hirose connectors.

The V+F3 unit operates over an input voltage range from 11 to 28 volts (30V max.). Polarity protection protects the electronics from improper power connection. A series of molded "Y" cables is used to interface with the zoom motor and the accessory connectors on most motion picture cameras.
