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.
