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 24-105mm f/4L 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.
If you use the EF 24-105mm f/4L IS USM lens for panned shots,
correction of camera shake might not be so effective.
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 <2>.
The Image Stabilizer is effective even when the camera is mounted on a
monopod.
Set the IS switch to <1>.
