Iris Lock

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.

1Set the Power Switch to “M” while pressing down the Lock Button located on the switch.

2Open the LCD monitor fully, or pull out the viewfinder fully.

3Set “p” to “MANUAL”. ( pg. 31, 34) ● The exposure control indicator appears.

4Adjust zoom so that the subject fills the LCD monitor or the viewfinder, then press and hold the MENU Wheel for over 2 seconds. The exposure control indicator and the “” indication appear.

5Press the MENU Wheel in. The “” indication

changes to “” and the iris is locked.

control...
