AF Mode Selection

Al Servo AF for Moving Subjects

While you press the shutter

button halfway, the camera

focuses continuously.

• This AF mode suits moving subjects

when the focusing distance keeps

changing.

• With predictive AF*, the camera can

also focus track a subject which

steadily approaches or retreats from

the camera.

• The exposure settings are set

immediately before the picture is

taken.

• When focus is achieved in the Al Servo AF mode, the viewfinder's in-focus

indicator does not light and the beeper does not sound.

• If the viewfinder's in-focus indicator blinks, focus cannot be achieved.

• The focus cannot be locked (except when Custom Function C.Fn-4 is set to 2.)

* About Predictive AF

If the subject approaches or retreats from the camera at a constant rate,

the camera tracks the subject and predicts the focusing distance

immediately before the picture is taken. This is for obtaining correct focus

at the moment of exposure.

With a manually selected focusing point, the focusing point will flash in red

and focus track the subject.

When the focusing point selection is automatic, the camera first uses the

center focusing point to focus. If the subject later moves away from the

center focusing point, focus tracking continues as long as the subject is

covered by another focusing point in the Area AF ellipse. The active

focusing point does not light.

fSigSi With Custom Function C.Fn-4-2, you can lock the focus momentarily by

pressing the <^> button even while the Al Servo AF is active. (->p.100)

Malil Custom Function C.Fn-11-2 enables you turn the <0> dial to change the

focusing point to track the subject in the Al Servo AF mode, (-^p.105)
