Canon EOS 650 - Manual (Page 15)

2. Setting the AF mode
This camera has two AF modes and the manual
focus mode.
ONE SHOT: Normal set position. The lens
stops moving once focus has been obtained.
As long as the shutter button is kept pressed
halfway, the original focus and exposure re­
main locked. This mode is useful when you
want your subject to be off-center.
• The shutter releases only after AF comple­
tion.
SERVO: The lens continues to rotate, refocus­
ing every time the focusing distance changes.
Use this mode to freeze subject motion at a
certain moment while following a moving sub­
ject. Exposure is determined at the moment of
shutter release.
• The shutter releases whether or not AF has
been completed.
MANUAL: Refer to p. 56.

1) Set the lens focus mode switch to “AF.”
