Preston Zoom Controller

Preston Micro Force V+F3 Zoom Controller

The Preston Micro Force V+F3 zoom control improves upon its heritage of ruggedness and precision with a new speed control sensor and digital speed display. The new sensor/control knob is virtually indestructible, and it turns with glassy smoothness. The design maintains the ergonomic advantages which have made the Micro Force the leading zoom control worldwide.

At the heart of the V+F3 is the same force sensor technology as the Micro Force. The V+F3 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 zoom function for the Preston FI+Z system, as well as interface with professional Canon and Fujinon video lenses (with 12-pin or 20-pin Hirose connector).

The V+F3 unit operates over an input voltage range from 12-28V (30V max.). A line of molded “Y” cables (sold separately) are used to interface the control with the zoom motor and the accessory connectors on most motion picture cameras. Available straight cables (sold separately) connect the V+F3 directly to video lenses or to the FI+Z Hand Unit.
