[] A Note on Wide-Angle Lenses
Autofocus may not provide the desired results with wide- and super-wide-angle lenses in
the following situations:
I The subject does not fill the focus point.
If the subject does not fill the focus point, the camera may
focus on the background and the subject may be out of focus.
2 The subject contains many fine details.
The camera may have difficulty focusing on subjects that
contain many fine details or that are lacking in contrast.
Example:A far-off portrait
subject at some distance
from the background
Example:A field of flowers
In these cases, use manual focus, or use focus lock to focus on another subject at
the same distance and then recompose the photograph. For more information, see
"Getting Good Results with Autofocus" (_ 40).
