4.5 Adjusting the Lens

Refer to the manual of each lens for the standard operation
of the lens. This section explains the operation unique to the
camera.
The B4 mount lens and B3 mount lens differ in their
operation. Please pay attention to the differences when
operating the lens.
4.5.1 How to Use the B4 Mount Lens
AUTO IRIS Operation
If the iris operation is too slow or, on the contrary, too fast
and causes hunting problems in the AUTO IRIS mode, adjust
the "IRIS GAIN" settings of the "AUTO IRIS SET" of the
"Maintenance Menu (2/3)". When the lens is installed in the
camera for the first time, or if the hunting problems still
exists or response is still slow even after the IRIS GAIN
settings are adjusted, adjust the auto iris sensitivity adjustment
trimmer of the lens using the following procedures:
1. Shoot the gray scale chart with the camera.
2. Set the "IRIS GAIN" to "50" by the camera menu.
3. Remove the rubber cap (with a Sens. IRIS GAIN marking
on it) of the grip on the front side of the lens, and
identify the auto iris sensitivity adjustment trimmer.
4. Using a Phillips screwdriver, rotate the auto iris
sensitivity adjustment trimmer fully clockwise as viewed
from the front of the lens to set the sensitivity to
maximum.
5. When hunting occurs, adjust the trimmer by gradually
reducing the sensitivity until the hunting problem is
corrected.
6. Make sure that hunting will not occur even when
changing the gain or covering the lens front with the
hand.
If hunting occurs, reduce the sensitivity until the problem
is corrected. Also, if the iris moves slightly with the
flickering light source such as a fluorescent lamp, reduce
the sensitivity until the iris becomes stable.
Be careful not to over-reduce the sensitivity. If overreduced,
not only the iris response will become slow, but also iris
adjustment accuracy will decrease. The response speed of
auto iris is set by the "IRIS SPEED" setting of the camera
menu. For the setting method, refer to "5.10.17 AUTO IRIS
SET (Setting the auto iris operation)".
