Tips on Using the Image Stabilizer
The Image Stabilizer cannot compensate for a
O O
blurred shot caused by a subject that moved.
Set the STABILIZER switch to OFF when you
O O
are taking pictures using the Bulb setting (long
exposures). If the STABILIZER switch is set to ON,
the image stabilizer function may introduce errors.
The Image Stabilizer might not be fully effective in
O O
the following cases:
• You shoot from a violently moving vehicle.
• You move the camera dramatically for a panning
shot in Mode 1.
The Image Stabilizer consumes more power than
O O
normal shooting, so fewer shots can be taken if you
use the function.
The image stabilizer operates for about two seconds
O O
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.
With Extender EF2× II attached to the lens, the
O O
Image Stabilizer will work with the following cameras:

E/50/50E, REBEL 2000/300, IX, IX Lite/IX7, and
D30, the Image Stabilizer will not work during self-
timer operation.
Using a tripod also stabilizes the image.
O O
However, depending on the kind of tripod and
shooting conditions, sometimes it may be better to
turn off the Image Stabilizer function.
The stabilizer is equally effective for hand-held
O O
photography and photography with a monopod. The
Image Stabilizer effect may be reduced, however,
depending on the shooting environment.
The Image Stabilizer also operates when the lens is
O O
used with extension tube EF12 II or EF25 II or the
extender EF1.4× III or EF2× III.
Depending on the camera there may be image
O O
shake, such as after releasing the shutter. However,
this does not affect shooting.
If you set the camera's Custom Function to change
O O
the assigned button to operate the AF, the Image
Stabilizer will operate when you press the newly
assigned AF button.
