THE SUBJECT IS DIFFICULT TO FOCUS IN THE AUTOFOCUS MODE
The autofocus mode uses the image contrast (the difference between light and dark parts) on the
CCD (Charge Coupled Device) to focus on. Therefore, with the autofocus mode, the focus may not be
adjusted correctly on the following subjects. In this case, use the focus lock function (see page 39).
The subject is too dark.
The subject has no
contrast such as a blue sky
or a white wall.
Some subjects at different
distances overlap in the
focus range.
The subject is too bright
such as a shining car body
or a surface of water.
