Exposure Control Iris Lock

EXPOSURE ± 0

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.
