Getting Good Results with Autofocus
Autofocus performs best when:
• There is contrast between the subject and the background. For example,
autofocus may not perform well on subjects that are the same color as the
background.
• The subject is evenly lit.
Autofocus does not perform well when:
• You attempt to focus simultaneously on two or more objects at different
distances from the camera. For example, autofocus may not perform well
when photographing an object inside a cage, because the bars of the cage
will be closer to the camera than the main subject, and both the bars and
the main subject will be in the focus area.
• The subject is very dark (the subject should not, however, be too much
brighter than the background).
• The subject is moving rapidly.
If the camera is unable to focus using autofocus, the autofocus indicator will
flash in the monitor or viewfinder when the shutter-release button is pressed
halfway. Use focus lock (
56) to focus on another subject at the same dis-
tance, or use manual focus ( 80).
Macro Close-Up
When the camera is zoomed out to or past the middle optical zoom position,
the macro close-up icon ( ) in the monitor or viewfinder will turn yellow, indi-
cating that macro close-up can be used to focus on objects as close a s 3 c m
(0.8˝) from the lens. To minimize distortion when shooting flat objects such as
printed text or business cards, however, we recommend that you zoom the camera
in and adjust the range until you find a distance at which focus can be achieved.
