About Auto Focus
Proper focus may be difficult or even impossible when
shooting the following types of subjects.
Solid color walls or subjects with little contrast
Strongly backlit subjects
Very shiny objects
Venetian blinds or other horizontally repeating patterns
Multiple subjects that are varying distances from the
camera
Subjects in poorly lit areas
Moving subjects
Subjects outside the shooting range of the camera
Proper focus may also be difficult or impossible if the
camera is moving.
Note that a green operation lamp and focus frame do not
necessarily guarantee that the resulting image will be in
focus.
If Auto Focus does not produce the results you want for
some reason, try using focus lock (page 87) or manual
focus (page 85).
When recording a dimly lit subject while Auto is selected
for the ISO sensitivity setting (page 142), the camera
increases sensitivity and uses a faster shutter speed.
Because of this, you need to guard against camera
movement if you have flash turned off (page 67).
Bright light shining on the lens can cause images to
appear washed out. This tends to happen when
recording images outdoors in bright sunlight. To protect
against this, use your free hand to shade the lens from
the light.
