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.
8Manual Focusing
1 Set the lens focus mode switch to
<MF>.
2 Focus the subject.
• Turn the lens focusing ring until the
subject looks sharp.
If you hold down the shutter button halfway while focusing manually, the AF
point achieving focus will flash in red and the focus confirmation light <n> will
light.
