5.2 How to Adjust Iris
5.2.1 Automatic iris lens
When using a lens without iris amplifier (DC) or iris amplifier built-in lens (VIDEO), connect
a 4P iris connector to the 4P terminal on the side surface of the camera body, and then
change the iris switch at the bottom of the camera body according to the lens. (Factory
setting: DC)
[How to adjust DC lens]
To obtain appropriate exposure (brightness), adjust SENS setting on the screen display
menu.
For how to operate, refer to the items “7.1 Selecting Screen” and “7.3 Setting SENS
(Sensitivity).”
[How to adjust Video lens]
(1) Set the AUTO mode setting “LEVEL” to “0”, “Peak/AVE” to “AVERAGE” and “AREA to
PRESET”.
(2) Select MANUAL mode for the SENS page of the screen display menu (refer to 7.3.2).
(3) Set the lens to Average.
(4) While shooting an object exposed to light as equally as possible, adjust the lens to

darkness from entering the image.
If measuring instrument such as waveform monitor is available, adjust the white level
to 50% by adjusting the lens side while all white area is being shot.

make adjustments by changing the “LEVEL” value of the setting item on SENS page
in the camera OSD menu.
