7-3 7. Relative Value Iris Control
7.2 Auto Iris Operation
During the auto iris operation, fine adjustment of approximately ± 1 stop for the F value
for auto iris control value is possible by using the IRIS control knob regardless of the
FULL switch condition. In addition, the actual fine adjustment is the additional value
with the control from other control panel.

Iris value retaining function
Some cameras have the function to keep the iris value when the value is switched
from the auto iris to the manual iris.
Caution
Check whether or not your camera has such function and fully understand
about the camera functions before start operating.
When the auto iris is switched to the manual iris, replacement to the manual file is
executed by inversely calculating from the iris control file. By conducting this operation,
the iris control file value becomes almost the same to the auto iris value, and the
variation of the iris value during switching can be kept to the minimum level.
