The V+F Lens control is 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. 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. Pressing the "Cal" button prompts the operator to match the lens iris openings at f2.8 and f16 to the camera. After calibration, the lens iris can be controlled in the following ways.
The FI+Z Hand Unit 3 is used for wireless operation with the wireless V+F Lens Control. 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
