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.
NOTES:
Iris lock is recommended in the following situa-
tions:
● When shooting on a reflective natural background
such as at the beach or when skiing.
● When shooting objects under a spotlight.
● When the subject is backing away.
● When zooming.
** Locking the exposure control and the iris
After step 1, adjust the exposure using the Zoom
Switch while holding SET. Then lock the iris in
step 2. For automatic locking, press SET quickly.
The iris becomes automatic after about 2
seconds.
Iris
Works like the pupil of the human eye. In a well-
lighted environment, the human pupil contracts to
keep too much light from enterintg. In low lighting,
the pupil dilates to allow more light in.
