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 lamp next to
the viewfinder will flicker when the shutter-release button is pressed halfway.
