Preston V+F Lens Control Single Channel Wireless Unit

Rent for $200.00 per day


The V+F Lens control is available as a single channel wireless/cable control (p/n 4050) or a cable only version (p/n 4051). Both are used with DM-1X or DM-2 digital motors. When used with video cameras and cinema style lenses, it allows control of the iris either through the camera or through a choice of hard wire or wireless controls. Wireless channels are indicated on the digital display (p/n 4050). A three position switch adjusts the motor torque level, and a second switch determines the direction of motor rotation. A simple calibration procedure sets up the iris of Cinema Style lenses to work with video cameras.


The FI+Z Hand Unit 3 (p/n 4060) is used for wireless operation with the wireless V+F Lens Control version 4050. The mode switch selects whether the unit responds to Focus, Iris, or Zoom commands. Camera Run/VTR signals are available for controlling all film and video cameras.

The Remote Iris Box (p/n 4020) may also be used in conjunction with the V+F Control for remote operation via a cable connection.

The unit operates over a voltage range of 11 – 30 VDC. For video cameras, all power and control signals are provided through the 12-pin Hirose on the camera. Film cameras having accessory receptacles capable of 1.5A @ 24V ( Arri 435, Panavision) can also be used to provide both power and camera run functions. Otherwise, separate receptacles are provided for external power and Camera Run/VTR.
