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 (˜). 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 f/number) of the lens becomes smaller than f/5.6, autofocusing will not operate. For details, refer to the extender's instructions. 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 feet. • Use your finger tip to touch the shutter button, grasp the camera with your entire right hand, then press the shutter button gently. 14
