5. When Autofocus Fails
The camera’s AF system is highly precise and can focus most subjects.
However, autofocus may not be achieved (the in-focus indicator blinks)
with certain subjects such as the following:
a. Very low contrast subjects.
Ex.: Blue sky; single-color, flat surfaces, etc.
b. Extremely backlit, reflective subjects.
Ex.: A highly-reflective car body.
c. Overlapping foreground and background subjects.
Ex.: A caged animal.
In such cases, lock the focus on an object at the same distance as the
subject and recompose or focus manually as described below.

* lens to M.

subject is in sharp focus.
