Autofocus can fail to achieve focus (viewfinder’s focus indicator <
o
>
blinks) with certain subjects such as the following:

Subjects with very low contrast
(Example: Blue skies, solid-color flat surfaces, etc.)

Subjects in very low light

Strongly backlit and reflective subjects
(Example: Cars with highly reflective bodies, etc.)

Near and distant subjects framed close to an AF point
(Example: Animals in cages, etc.)

Subjects such as dots of light framed close to an AF point
(Example: Night scenes, etc.)

Repetitive patterns
(Example: Skyscraper windows, computer keyboards, etc.)
In such cases, focus by doing either of the following:
(1) With One-Shot AF, focus on an object at the same distance as the
subject and lock the focus, then recompose the shot (p.61).
(2) Set the lens’s focus mode switch to < MF > and focus manually.

Focus by turning the lens’s focusing
ring until the subject looks sharp in
the viewfinder.
Subjects Difficult to Focus on
MF: Manual Focus

Depending on the subject, focus may be achieved by slightly
recomposing the shot and performing AF operation again.

If you press the shutter button halfway during manual focusing, the AF point

focus indicator <
o
