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.
