When Autofocus Fails (Manual Focusing)

Autofocus can fail to achieve focus (the focus confirmation light <n> blinks) with certain subjects such as the following:

Difficult Subjects for Autofocusing

Low-contrast subjects.

Example: Blue sky, flat surface with a solid color.

Subjects in very low light.

Extremely backlit or reflective subjects. Example: Automobile with a strong reflection.

Overlapping near and far objects. Example: Animal behind bars in a cage.

In such cases, do one of the following:

(1)Focus lock an object at the same distance as the subject and recompose.

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