halfway, the focus will be locked. You can then recompose the shot if desired.

In the d/s/f/a/Fshooting modes, AF is also possible by pressing the <p> button.

If focus cannot be achieved, the focus confirmation light <o> in the viewfinder will blink. If this occurs, a picture cannot be taken even if the shutter button is pressed completely. Recompose the picture and try to focus again. Or see “When Autofocus Fails” (p.84).

If the [1Beep] menu is set to [Off], the beeper will not sound when focus is achieved.

This AF mode is for moving subjects when the focusing distance keeps changing. While you hold down the shutter button halfway, the subject will be focused continuously.

The exposure is set at the moment the picture is taken.

In the d/s/f/a/Fshooting modes, AF is also possible by pressing the <p> button.
