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.

1 Set the Power Switch to “M”.

2 Set “p” to “MANUAL”. (
pg. 31)

●The exposure control indicator appears.

3 Adjust zoom so that the subject fills the LCD monitor or the viewfinder, then press and hold MENU for over 2 seconds. The exposure control indicator and the “” indication appear.

4 Press MENU. The “” indication changes to “” and the iris is locked.

To return to automatic iris control

Select “AUTO” in step 2. Or, set the Power Switch to “A”.

●The exposure control indicator and “” disappear.

To lock the exposure control and the iris

After step 2, adjust the exposure by pressing + or –. Then lock the iris in steps 3 and 4. For automatic locking, select “AUTO” in step 2. The exposure control and the iris become automatic.
