Olympus iS-3 DLX Instructions Manual page 69

The five pictures below are samples taken using
the zoom lens. Notice the dimensions of the subject
as the camera zooms in.
Be sure to hold the camera firmly or use a tripod,
as pictures tend to blur more easily at longer focal
lengths. Setting the shutter speed at 1/250-sec. or
faster is recommended.
Angle of view and depth of field
Angle of view is directly related to the focal depth of
field (the distance in front of and behind the subject
that the camera is able to bring into focus). The
greater the angle of view (wide angle), the greater
the depth of field. When the angle of view is
narrow (telephoto), the depth of field decreases.
The use of a converter lens (optional)
It is possible to attach a converter lens for an even
wider angle of view, or for additional telephoto
power.
Instead of 35 mm, a wide-angle converter (0.8X)
enables you to reduce the camera's focal length
to 28 mm.
Instead of 180 mm, a telephoto converter (17X)
enables you to increase the camera's focal length
to 300 mm.
