The Motion Picture Academy awarded a 2007 Scientific and Engineering Award for the development of the FI+Z system to Howard Preston and Mirko Kovacevic in recognition of its contribution to the motion picture industry.

Also in 2007, the Society of Camera Operators presented a Technical Achievement Award to Howard Preston for his work on the FI+Z and Light Ranger.

We want to express our thanks to both organizations for this important recognition.





The newest member of the FI+Z system is the Hand Unit 3 (HU3). It fits brilliant functionality and performance into a splash resistant housing. The on-board lens library stores data on 150 lenses. "Lens Mapping" software matches the lens library data to pre-printed Focus Rings, eliminating a time consuming chore. Camera speed and shutter angle can be programmed. The bright OLED display shows camera, lens and Hand Unit status. The molded, detachable, hand grip provides all-day comfort. White LED's automatically illuminate the Focus Marking Ring under low light conditions. The HU3 is compatible with both the MDR2 3-channel motor driver and the VLC single channel motor driver.





The Focus/Iris (F/I) unit is a wireless, single channel control. It can be used with the FI+Z system to take over the Iris or Focus function from the FI+Z Hand unit. When the F/I unit is powered, the FI+Z motor driver recognizes its presence and gives it control of either the Focus or Iris function of the FI+Z Hand unit as selected by the user.

The Focus/Iris unit can also be used with the single channel V+F Lens Module to control a single DM-1 or DM-2 digital motor. Together they form a complete, single channel lens drive system with camera run functions.

Additionally, this unit can also be used in conjunction with the Radio Dimmer unit to control LED Eye-Lights.





The V+F Lens Control is a single channel lens control unit for driving a digital motor and controlling Camera Run/VTR.

The wireless version (p/n 4050) can be controlled in any of the following ways:

  • FI+Z Hand Unit
  • Radio Micro Force.
  • Local control with the control knob
  • Remote cable connection with a Remote Iris Box (p/n 4020)
  • Video Camera Control: either through a Sony RMB type control or through the camera's internal exposure control.

    The Video Lens Control (p/n 4051) is a minimum cost version without wireless capability. It is the perfect solution for using cinema style lenses with video cameras.





    The The Radio Micro Force module adds wireless operation to either the Analog V+F2 or Digital Micro Force Models. It can be used to control the zoom channel of an MDR2, wireless V+F Lens control or Radio Dimmer. Lens position and limits are shown on the bright LED bargraph display.
