4.1.6 Specifying Iris Gain 
[I-Gain]
Specifying Auto Iris Gain
 
Although this value is factory-set, it can be adjusted as needed.
To adjust the value, use either the auto iris gain adjustment trimmer (refer to the Lens Manual) or display operations. 
Regardless of the method of adjustment used, the most recent setting takes precedence.
The same auto iris gain value applies to all users, regardless of the current user. Thus, there is no need to switch users 
in advance. Unlike most other setting adjustments, any changes to this setting also apply to user 0.

Note:   Do the following when 
adjusting gain while checking 
iris operation.
     
→ Confi rm that the drive unit A/M 
switch is set to [Auto] mode.
     
→  Set the camera iris mode to 
[Auto].
Note:   As you look at the lens iris 
ring, set it to the position of 
maximum gain at which “focus 
hunting” does not occur.
Note:   The current iris gain value 
is retained even if you reset 
other settings as described in 
“4.2.1 Resetting Values.” For 
this reason, you will no longer 
be able to view the default 
setting. If necessary, make 
a note of the default setting 
before adjusting this value.
