When Autofocus Fails
Autofocus can fail to achieve focus (the focus confirmation light <O>
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.)
® 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.56).
(2) Set the lens focus mode switch to <MF> and focus manually.
