The focus-lock function is used when the subject is off- center and outside the focus frame. Focus lock may also be used when a special focusing situation prevents the camera from focusing on the subject.
Place the subject within the focus frame. Press and hold the shutter-release button partway down (1). The focus signals indicates that the focus is locked. When the focus is set, an AF area is illuminated briefly to indicate the point of focus.
Without lifting your finger from the shutter-release button, recompose the subject within the viewfinder. Press the shutter-release button all the way down to take the picture (2).
CAMERA-SHAKE WARNING
If the shutter speed falls below the point where the camera can be hand held safely, the camera-shake warning indicator blinks in the viewfinder. Camera shake is slight blurring caused by subtle hand motion and is more pronounced with telephoto lenses than wide angle. Although the warning appears, the shutter can still be released. If the warning appears, place the camera on a tripod or use the built-in flash.
