NOTE: Digital zoom reduces the resolution of an image, so
your picture may be more grainy than the same image
taken with optical zoom. When you need higher quality,
limit the use of digital zoom.
NOTE: Digital zoom is not available while recording video
clips, in the Panorama modes, nor in the Super Macro
focus setting.
Zoom and Focus
The more you zoom in on the subject of your picture, the
more small movements of the camera are magnified (this is
called camera shake). If appears when you press the
Shutter button halfway down, you are moving the camera or
the scene needs more light; the picture will likely be blurry.
Try holding the camera closer to your body or against a
steady object, or set the camera on a tripod or stable
surface. Also try turning on the flash or turning on lights to
add more light to the scene.
TIP: Increasing ISO Speed (see page 76) can help reduce
camera shake, but can result in increased noise in your
images.
Also, when the camera is in Normal, Manual, or Infinity
focus range settings, the zoom indicator has a notch. When
the green marker is to the right of the notch, be sure that your
subject is within the Normal focus range (see page 42);
otherwise the picture will likely be blurry.
