NOTES:
● Be sure to focus the lens in the maximum telephoto position
when you use the Manual Focus mode. If you focus in on a
subject in the wide-angle position, sharply focused images
cannot be obtained when zoomed up because the depth-
of-field is reduced at longer focal lengths.
● When the focus level cannot be adjusted any further or
closer, “
” or “
” will blink.
Manual exposure control is recommended in the
following situations:
● When shooting using reverse lighting or when the
background is too bright.
● When shooting on a reflective natural background such as
at the beach or when skiing.
● When the background is overly dark or the subject is bright.

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.
