USM lens, the Image Stabilizer will not be very effective while you move
the camera to take panned shots.

The Image Stabilizer can operate with the focus mode switch set to
either <AF> or <MF>.
• If the camera is mounted on a tripod, you can save battery power by
SWitching the IS switch to
<OFF>.
• The Image Stabilizercan operate even when the camera is mounted on
a monopod.
.. Some IS lenses enable you to switch the IS mode manually to suit the
shooting conditions. However, the EF-S 18-200mm f/3.5-5.6 IS and EF-
S18-55mm f/3.5-5.6 IS lenses switch the IS mode automatically.
