FOCUSING
SPECIAL FOCUSING CONDITIONS
In the autofocus mode, the camera uses the image contrast (the difference between bright
and dark components) on the CCD (charge-coupled device) for focus detection. This is why
there are certain types of subject that are unsuitable for autofocusing. In such a case use focus
lock (see page 38): Sight a subject detail at the same distance as your main subject and lock
focus. Alternatively, you may switch to manual focusing (see page 39).
Subject too dark.
Subject contrast too low (e.g. blue sky or
white wall).
Autofocus area captures detail at different
distances.
Subject too bright (e.g. highly reflecting car
paint or glittering water surface).
