Canon EOS A2 - Selecting the AF Mode

3. Selecting the AF Mode
Three types of autofocusing are available:
One-shot AF, Al Servo AF and Al Focus AF. Al
Focus AF is active only in Full Auto ( O )
mode. Manual focusing is also available.
a)
When the subject is focused in One-shot AF
mode, the corresponding AF frame lights red in
the viewfinder, and the in-focus indicator lights
up. At the same time, the shutter speed and
aperture value are displayed in the viewfinder
and LCD panel.
If you remove your finger after pressing the
shutter button to the halfway position, the in-
focus indicator will disappear, but the camera
timer will keep the viewfinder and LCD panel
displays lit for six seconds.
1) Press the AF mode button. If you release
the button, the timer will allow AF mode se-
lection for six seconds.
2) Operate the main dial so the desired AF
mode indicator appears in the LCD panel.
* Make sure the lens’ focus mode switch
is set to AF for autofocus shooting.
One-shot AF
Use this mode with stationary subjects. The
shutter will not release until the subject is fo-
cused. Exposure is determined when the
subject is focused. By keeping the shutter
button pressed to the halfway position, the
focus
and
exposure
settings
remain
locked,
allowing
you
to
recompose
the
picture
as
desired.
© The shutter will not release if the in-focus
indicatoris
still
blinking,
Try
refocusing
the
subject at a different position or use ma-
nual focusing (refer to page 23).
