Canon EOS 300 User Manual

When Autofocus Fails (Switching to Manual Focus) s
The camera has a high-precision AF system which can focus almost all
subjects. However, it can fail to achieve focus (the in-focus indicator blinks)
with the subjects listed below.
Difficult Subjects for Autofocusing
(a) Low-contrast subjects.
Example: Blue sky, solid colors on a flat surface, etc.
(b) Extremely backlit or reflective subjects.
Example: Automobile with a highly reflective finish.
(c) Overlapping near and far objects.
Example: Animal behind bars in a cage.
In such cases, focus an object at the same distance as the subject and lock
the focus before recomposing. (See page 39) Or focus manually by
following the procedure below.
Manual Focusing
роосопоопоб [UJUUUUUUU| :
Set the lens focus mode switch to
MF (or M on older lenses).
Turn the lens focusing ring until
the subject is in focus in the
viewfinder.
