Shooting Problem Subjects for the Autofocus
Available in the following modes.
The autofocus may not work well on the following types of
subjects.
• Subjects with extremely low contrast to the surround-
ings
• Subjects mixing close and far objects
• Subjects with extremely bright objects at the center of
the composition
• Subjects that are moving quickly
To shoot these subjects, first aim the camera at an object
at a similar distance, lock the focus and recompose the
image with the desired subject, or use manual focus.

happens.
