When Autofocus Fails (Manual Focusing)
Autofocus can fail to achieve focus (the focus confirmation light <•>
blinks) with certain subjects such as the following:
(a) Low-contrast subjects (blue sky, solid-color walls, etc.).
(b) Subjects in low light.
(c) Extremely backlit and reflective subjects (car with a reflective body,
etc.).
(d) Overlapping near and far objects (animal in a cage, etc.).
In such cases, do one of the following:
1. Focus an object at the same distance as the subject and lock the
focus before recomposing.
2. Set the lens focus mode switch to <MF> and focus manually.

select the center AF point. An off-center AF point may not be able to
achieve focus.
