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 may not be effective if the subject moves at the time
of exposure.
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-
S18-135mm f/3.5-5.6 IS lenses switch the IS mode automatically.
