The reference value for automatic iris adjustment can be changed to

special effects. The reference value for the lens iris can be set within the
following range with respect to the standard value as defined by an F
number.
• 0.5: about 0.5 stop further open
• 0.25: about 0.25 stop further open
•
−
0.25: about 0.25 stop further closed
•

0.5: about 0.5 stop further closed
To change the reference value, set A. IRIS OVERRIDE to ON (factory
setting is OFF) on the FUNCTION 2/2 page of the setup menu.
The reference value is normally set to the standard value. Even if the
reference value is changed, it reverts to the standard value every time the
power is turned on.
