Image Stabilizer ¡The Image Stabilizer cannot compensate for a blurred shot caused by a subject that moved. ¡Set the STABILIZER switch to when you are taking pictures using the Bulb setting (long exposures). If the STABILIZER switch is set to , the image stabilizer function may introduce errors. ¡The Image Stabilizer might not be fully effective in the following cases: • You move the camera for a panned shot. • You shoot while riding on a bumpy road. ¡The Image Stabilizer consumes more power than normal shooting, so fewer shots can be taken if you use the function. ¡The image stabilizer operates for about two seconds even when your finger is off the shutter button. Do not remove the lens while the stabilizer is in operation. This will cause a malfunction. ¡When you use a tripod, the Image Stabilizer should be turned off to save battery power. ¡The stabilizer is equally effective for hand-held photography and photography with a monopod. ¡The image stabilizer function also operates when the lens is used with an Extension Tube EF12 ll. ¡Pictures may look distorted after being taken depending on the camera, but this doesn't affect shooting. ¡If you set the camera's Custom Function to change the assigned button to operate the AF, the Image Stabilizer will operate when you press the newly assigned AF button.
