During autofocus operation, you can press the
AF stop button to temporarily pause autofocus.

If the shutter button is still pressed halfway when
the AF stop button is released, autofocusing will
continue as before.

• With the EOS 630/600, RT, A2/A2E/5, or 10S/10

set to the AI Servo AF mode and continuous
shooting, AF will not resume even after you let
go of the AF stop button. Press the shutter
release button halfway to resume AF.

• With the EOS A2/A2E/5 and 10S/10 set to the

Sports mode, AF will not resume even after you
let go of the AF stop button. Press the shutter
release button halfway to resume AF.

• The AF stop function also works in AI Servo AF

mode.

• By setting the camera's Custom Function, you

can change the AF stop button's function. For
details, see the camera's instruction manual.
