How the Shutter Button Works
The EOS camera's shutter button can be depressed halfway or ail the way.
There is a click stop at the halfway point.
Pressing the Shutter Button Halfway or Completely
The shutter button works as described below.
When it is pressed halfway:
• Autofocusing is activated, and when
focus is achieved, the beeper sounds
and the in-focus indicator <•> on the
viewfinder's lower right also lights.
• Also, the shutter speed and aperture
are set and displayed on the LCD
panel and In the viewfinder.
When It is pressed completely:
• The shutter is released to take the
picture and the film advances by one
frame.
If an Extender is used and the maximum aperture of the lens becomes smaller
than f/5.6 (larger f-number), autofocusing will not operate.
1^ Camera movement during the moment of exposure is called camera shake.
Camera shake can cause blurred pictures. To prevent blurred pictures due to
camera shake:
• Hold the camera steady (->page 22).
• Use the center of your finger to touch the shutter button, grasp the camera with
your entire right hand, then press the shutter button gently.
