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 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 <> (or <> on older lenses) and focus manually. (→p.26)

If focus cannot be achieved with the AF-assist light of a Speedlite or ST-E2, select the center AF point. An off-center AF point might not be able to achieve focus.
