I 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.

size in the LCD monitor or the viewfinder
changes), such as when the subject is backing
away.

such as at the beach or when skiing.
