Like the pupil of the human eye, the iris contracts in
well-lit environments to keep too much light from
entering, and dilates in dim environments to allow
in more light.
Use this function in the following situations:
● When shooting a moving subject.
● When the distance to the subject changes (so its
size in the LCD monitor or the viewfinder
changes), such as when the subject is backing
away.
● When shooting on a reflective natural background
such as at the beach or when skiing.
● When shooting objects under a spotlight.
● When zooming.
When the subject is close, keep the iris locked. Even
when the subject moves away from you, the image
will not darken or brighten.
Before starting, perform the procedures listed
below:
● Set the Power Switch to “M” while pressing down
the Lock Button located on the switch.
● Open the LCD monitor fully, or pull out the
viewfinder fully.

2 seconds.
Backlight Compensation
Backlight compensation brightens the subject
quickly.
Press BACKLIGHT. The indicator is displayed
and the subject is brightened. If pressed again,
disappears and the brightness returns to the previous
level.
● Using BACKLIGHT Button may cause the light
around the subject to become too bright and the
subject to become white.

the Power Switch is set to “A”.
