When Autofocus Fails uc^nitm j ^ • x ^
The camera has a high-precision AF system which can focus almost all
subjects. However, it can fail to achieve focus (the focus confirmation
light <•> blinks) the subjects listed below.
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, use one of the following methods to focus:
(1) Focus lock an object at the same distance as the subject and
recompose
(2) Set the lens focus mode switch to <MF> or <M> and focus manually
as explained below.
