About the Lens Image Stabilizer

When you use the IS lens' built-in Image Stabilizer, camera shake is
corrected to obtain a less blurred shot. The procedure explained here is
based on the EF-S18-55mm f/3.5-5.6 IS lens as an example.
* IS stands for Image Stabilizer.
The Image Stabilizer is not effective for moving subjects.
The Image Stabilizer may not be effective for excessive shaking such as
on a rocking boat.
The Image Stabilizer can operate with the focus mode switch set to
either <f> or <g>.
If the camera is mounted on a tripod, you can save battery power by
switching the IS switch to <2>.
The Image Stabilizer is effective 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-S18-55mm f/3.5-5.6 IS and EF-
S18-200mm f/3.5-5.6 IS lenses switch the IS mode automatically.
