Iris Lock
Use this function when shooting a moving subject, when
zooming, when the subject changes its distance (thus its
size in the viewfinder), or when you want to lock the
brightness level.
When the subject is close, keep the iris locked. Even when
the subject moves away from you, the image will not
darken or brighten.

Iris
Works like the pupil of the human eye. In a well-lit
environment, the human pupil contracts to keep too much
light from entering. In low lighting, the pupil dilates to
allow more light in.
