Description.  

 

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-1 or DM-2 digital motors. The cable only version 

is intended to control the iris function of cinema style lenses mounted on video cameras. In this 
mode, the iris is controlled through: 

 

x

 

the cameras’ remote set-up box (Sony RMB-150 or equivalent)  

x

 

through the cable connected Remote iris Box (p/n 4020)  

x

 

through the on-board control knob. 

 
The wireless version adds the possibility of control through any of three wireless hand units: 
 

x

 

Focus-Iris Hand Unit  

 

 

(p/n 4024) 

x

 

FI+Z Hand Unit   w/ MW Transmitter 

(p/n 4000 + 4910) 

x

 

Radio Micro Force unit   

 

(p/n 4015 or 4016) 

 
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. 
The small size of the control makes it especially suitable for hand held use. 
 
The FI+Z Hand Unit (p/n 4000 with Microwave Transmitter p/n 4910), the Focus-Iris Hand Unit 
(p/n 4024) or the Radio Micro Force (p/n 4015 or 4016) can all be used for wireless operation 
with version p/n 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 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.
