Subjects that are difficult to focus on

The autofocus mechanism is not perfect. Focusing may be difficult
when taking pictures under the following conditions. These also apply
to manual focusing using the focus indicator ] in the viewfinder.

(a) Extremely low-contrast subjects such as a white wall in the

focusing area

(b) Subjects which do not reflect much light within the focusing

area

(c) Fast moving objects
(d) Strongly reflected light or strong backlighting (bright

background)

(e) If repeating vertical or horizontal line patterns appear within

the focusing area

(f) Multiple subjects in the foreground and background within the

focusing area

If the subject cannot be focused automatically, set the focus mode
lever to \ and use the manual focus mode to focus on the subject
with the aid of the matte field in the viewfinder. (p.122)

The subject may not be focused even when the ] (focus indicator) is
displayed when (e) and (f) above apply.
