The Preston MicroForce Zoom Control is a handheld controller that provides precise, smooth control over your zoom lens. The controller is compatible with a wide range of lenses and can be used for both cinema and broadcast applications to provide the zoom command signal for the FI+Z system as well as drive the internal motors of most video lenses. The control drives a wide range of analog motors from M26T Heden motors to the full range of Panavision zoom motors. 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 the 12 pin or 20 pin Hirose connector). Its ergonomic design provides a rounded grip for comfortable use throughout the day and also offers a convenient fixing point for your docking arm adapter. The V+F3 unit operates over an input voltage range from 12 to 28 volts (30V max.). A series of molded "Y" cables is used to interface the control with the zoom motor and the accessory connectors on most motion picture cameras. Straight cables connect the V+F3 directly to video lenses or to the FI+Z Hand Unit.
