3 OPERATION 3-2 Iris Operation Normally, lens iris operation is performed by the position servo control method using commands from the camera CCU. Control can be switched between auto iris control and remote iris control. The camera operator can also perform remote iris control using a switch box (special version) as a special specification. Control from the Camera Control from the Switch Box When a switch box which is capable to control the iris function of the lens is mounted, the iris function of the lens is controlled by it. Setting the iris control select switch Settings must be performed at the lens side in order for the iris to be controlled from the switch box. Follow the setting steps below. Both automatic and remote iris control are usually operated from the CCU. (Refer to the camera operation manual on how to operate.)

below.
Turning the knob clockwise:
The iris moves in the opening direction.
Turning the knob counterclockwise:
The iris moves in the closing direction.
Iris Control Knob
As when the iris is to be controlled from the camera, the
approximate F number can be monitored on the indicator
panel.
* (NOTE)
•
See the section “Mounting the Switch Box” (p. E3) for details of
how to mount and connect the switch box.
•
Refer to the table “Iris mode” in the section 2-5 “Iris Mode Setting
