Getting good results with
autofocus
Autofocus does not perform well under the conditions
listed below. If the camera is unable to focus using
autofocus, use manual focus (➝p.60) or use focus lock
(➝p.61) to focus on another subject at the same distance
and then recompose the photograph.
There is little or no contrast
between the subject and the back
ground.
Example: subject is the same
color as the back ground.
The focus area contains objects at
different distances from the
camera.
Example: subject is inside a cage.
The subject is dominated by
regular geometric patterns.
Example: a row of windows in a
skyscraper.
The focus area contains areas of
sharply contrasting brightness.
Example: subject is half in the
shade.
The subject appears smaller than
the focus area.
Example: focus area contains
both foreground subject and
distant buildings.
The subject contains many fine
details.
Example: a field of flowers or other
subjects that are small or lack
variation in brightness.
