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-S 15-85mm f/3.5-5.6 IS USM 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.
With the EF 28-135mm f/3.5-5.6 IS 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 lens 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 <2>.
The Image Stabilizer can 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 15-85mm f/3.5-5.6 IS USM,
EF-S 18-135mm f/3.5-5.6 IS, and EF-S 18-200mm f/3.5-5.6 IS lenses
switch the IS mode automatically.
