Tips on Using the 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
e xposures). 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:
•Y ou shoot while riding on a bumpy road.
•Y ou move the camera dramatically for a
panning shot in Mode 1.
•Y ou shoot using techniques other than
f ollowing shots in Mode 2.
• 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
bu tton. Do not remove the lens while the stabilizer
is in operation. This will cause a malfunction
.
• With the EOS-1V/HS, 3, ELAN 7E/ELAN
7/30/33, ELAN 7NE/ELAN 7N/30V/33V, ELAN
II/ELAN IIE/50/50E, REBEL 2000/300, IX, and
D30, the Image Stabilizer will not work during
self-timer operation.
• Using a tripod also stabilizes the image.
However, depending on the kind of tripod and
shooting conditions, sometimes it may be better
to turn off the Image Stabilizer function.
•Ev en with a monopod, the Image Stabilizer will
be as effective as during hand-held shooting.
However, depending on the shooting
environment, the Image Stabilizer effect may be
less effective.
• The image stabilizer function also operates
when the lens is used with an Extension Tube
EF12 ll or EF25 ll.
• Pictures may look distorted after being taken
depending on the camera, but this doesnt 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.

8.Infinity Compensation Mark9. Infrared Index
Infinity compensation markDistance index
To  compensate for shifting of the infinity focus
point that results from changes in temperature.
The infinity position at normal temperature is the
point at which the vertical line of the L mark is
aligned with the distance indicator on the
distance scale.
F or accurate manual focusing of subjects at
infinity, look through the viewfinder or look at the
magnified image* on the LCD screen while
rotating the focusing ring.
* For cameras with Live View shooting capability.
The infrared index corrects the focus setting when using
monochrome infrared film. Focus on the subject
manually, then adjust the distance setting by moving the
f ocusing ring to the corresponding infrared index mark.
• The infrared index position is based on a
wav elength of 800 nm.
•
The compensation amount differs depending on
the focal length. Use the indicated focal length as
a guide when setting the compensation amount.
• Be sure to observe the manufacturer’s
instructions when using infrared film.
• Use a red filter when you take the picture.
Some EOS cameras cannot use infrared film. See
the instructions for your EOS camera.
