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.
