About the Lens Image Stabilizer

When you use the IS lens' built-in Image Stabilizer, camera shake is
corrected to obtain a sharper shot. The procedure explained here is
based on the EF-S18-55mm f/3.5-5.6 IS II lens as an example.
* IS stands for Image Stabilizer.
The Image Stabilizer cannot correct "subject blur", when the subject
moves at the time of exposure.
For bulb exposures, set the IS switch to <2>. If <1> is set, Image
Stabilizer misoperation may occur.
The Image Stabilizer may not be effective for excessive shaking such as
on a rocking boat.
The Image Stabilizer can operate with the lens focus mode switch set to
either <AF> or <MF>.
When using a tripod, you can still shoot with the IS switch set to <1>
with no problem. However, to save battery power, setting the IS switch to
<2> is recommended.
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 following lenses switch the IS mode
automatically:
• EF-S18-55mm f/3.5-5.6 IS II
• EF-S15-85mm f/3.5-5.6 IS USM • EF-S18-200mm f/3.5-5.6 IS
Set the IS switch to <1>.
