How the Shutter Button Works
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 20).
· Use your finger tip to touch the shutter button, grasp the camera with your
entire right hand, then press the shutter button gently.
Pressing the Shutter Button Halfway or Fully
When it is pressed halfway:
•
Autofocusing (AF) is activated.When
the subject is in focus, the AF point
which achieved focus will flash, the
beeper will sound, and the focus
confirmation light will light up.
•
Also, the shutter speed and aperture
are set and displayed on the LCD
panel and in the viewfinder.
When it is pressed fully:
•
The shutter is released to take the
picture and the film advances by one
frame.
The EOS camera’s shutter button can be depressed halfway or all the
way. There is a click stop at the halfway point.
The shutter button works as described below.
If an Extender is used and the maximum aperture of the lens becomes small-
er than f/5.6 (the lowest f/number), autofocusing will not operate.
