Auto Focus
When you press the Shutter button halfway down, the
camera automatically measures and locks the focus and
exposure. This is called auto focus. The following table
describes the indicators in the Image Display when you auto
focus:
Focusing on the Subject
When the camera is set to its default
Multi focus area setting (see
page 74), it uses the five focus
regions within the focus brackets,
shown at right, to determine focus.
When you press the Shutter button
halfway down, the camera
searches for focus starting from the
closest distance. When it finds focus
in one region, it then examines
other focus regions, displaying
those in focus as green brackets. In
the image to the right, the camera
has found focus in regions one, two, and five.
Indicator Possible Solutions
Green focus brackets The camera has found focus.
Red focus brackets The camera cannot find focus (see
