How the Shutter Button Works
The shutter button has two stages. You can press it down halfway or
fully. The two levels of shutter button operation are as follows:
When it is pressed halfway:
• Pressing the shutter button down
halfway activates autofocusing
(AF), and also activates the
automatic exposure (AE)
mechanism and sets the shutter
speed and aperture value.
• The exposure (the combination of
shutter speed and aperture value)
appears on the LCD panel and in
the viewfinder ((S4).
When it is pressed fully:
• The shutter is released to take the
picture and the film advances by
one frame.
If an Extender (optional) is used and the maximum aperture (the
lowest t/number) of the lens becomes smaller than f/5,6,
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.
• Firmly grasp the camera grip with your right hand, and press
your both elbows lightly against your body.
• Hold the lens at the bottom with your left hand.
■ Press the camera against your face and look through the viewfinder.
• To maintain a stable stance, place one foot in front of the other
Instead of lining up both feel.
• Use your finger tip to touch the shutter button, grasp the camera
with your entire right hand, then press the shutter button gently.
