Shutter Speed and Moving Subjects
Your choice of shutter speed is an important factor in determining how
moving subjects will appear in the final image. Depending on the speed of
your subject, slower shutter speeds such as 1/15 sec. will make moving
subjects appear blurred and flowing in the picture, creating a greater feeling
of motion. Fast shutter speeds, of course, are useful to freeze fast action.
Also, if you are using a telephoto lens, a fast shutter speed can help prevent
blurring caused by camera shake. For lenses longer than f'= 50mm, a
general rule to follow is that 1/f is the slowest usable shutter speed while the
camera is being hand-held. For example, if you are using a 135mm lens, try
to avoid using shutter speeds slower than 1/200 sec. (the closest shutter
speed to 1/135) without mounting the camera on a tripod.
The action index provides a simple way for you to visualize approximately
how your subject will appear in the final picture. The camera's expert system
compares the speed of your subject's image and compares it to the shutter
speed you have selected. It then positions the indicator to illustrate roughly
how much the image will be blurred.
