When Autofocus Fails

Autofocus can fail to achieve focus (viewfinder’s 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 and 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 either of the following:

(1)With One-Shot AF, focus an object at the same distance as the subject and lock the focus before recomposing the shot (p.75).

(2)Set the lens focus mode switch to <MF> and focus manually (p.110).

For subjects difficult to focus during Live View shooting or movie shooting with [u+Tracking], [FlexiZone - Multi], or [FlexiZone - Single], see page 241.
