Shooting Particular Scenes
Getting Good Results with Autofocus
Autofocus does not perform well under the conditions listed below. The shutter
release may be disabled if the camera is unable to focus under these conditions,
or the in-focus indicator (A) may be displayed and the camera may sound a
beep, allowing the shutter to be released even when the subject is not in focus. In
these cases, use manual focus (A 61) or use focus lock (A 60) 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
background (e.g., the
subject is the same
color as the background).
The focus point
contains objects at
different distances
from the camera (e.g.,
the subject is inside a
cage).
The subject is
dominated by
regular geometric
patterns (e.g., a row
of windows in a
skyscraper).
The focus point
contains areas of
sharply contrasting
brightness (e.g., the
subject is half in the
shade).
Background objects
appear larger than
the subject (e.g.,
focus point contains
both foreground
subject and distant buildings).
The subject contains
many fine details
(e.g., a field of flowers
or other subjects that
are small or lack
variation in brightness).
