An iris gain control hole is usually provided in the front of the
lens. Adjustment of the iris gain, with a screwdriver through
the hole may be done as follows. (Shape and location of the
hole may vary depending on the type of lens.)
1. Turn the iris selection switch to Position A (AUTO).
2. Rotate the iris gain control to the maximum gain, but in a
range where no hunting or oscillating of the iris ring
develops.
