When Autofocus Fails
Autofocus can fail to achieve focus (the focus confirmation light
<.

blinks) with certain subjects such as the following:
Subjects difficult to focus
• Very low-contrast subjects
(Example: Blue sky, solid-color walls, etc.)
• Subjects
in
very low light
• Extremely backlit or reflective subjects
(Example: Car with a highly reflective body, etc.)
• Near and far subjects covered by
an
AF point
(Example: Animal
in
a cage, etc.)
4)
Repetitive patterns
(Example: Skyscraper windows, computer keyboards, etc.)
In
such cases, do one
of
the following:
(1) With One-Shot
AF,
focus
an
object at the same distance as the
subject and lock the focus before recomposing (p.52).
(2) Set the lens focus mode switch to <MF> and focus manually.
