However, for the 122 mm focal length, your shutter speed of 1/100 second is slow. A rule of thumb for hand-held shooting is to use a shutter speed of at least as fast as the reciprocal of your focal length.  For this example, using a shutter speed of 1/100 would cause you to zoom your focal length back to 100mm or less, or to change your shutter speed to 1/122 second or faster, so it could be set to 1/125 second or faster.  WM</blockquote>
