Autofocus can fail to achieve focus (viewfinder’s focus confirmation light
<
o
> blinks) with certain subjects such as the following:
Very low-contrast subjects
(Example: Blue skies, solid-color flat surfaces, etc.)
Subjects in very low light
Extremely backlit and reflective subjects
(Example: Cars with highly reflective bodies, etc.)
Near and far subjects covered by an AF point
(Example: Animals in cages, etc.)
Repetitive patterns
(Example: Skyscraper windows, computer keyboards, etc.)
In such cases, do either of the following:
(1) With One-Shot AF, focus on an object at the same distance as the
subject and lock the focus before recomposing the shot (p.59).
(2) Set the lens’s focus mode switch to < MF > and focus manually.

the viewfinder.
