f/5.6L IS USM is a high-performance super-
telephoto lens equipped with an Image
Stabilizer.
• "IS" stands for Image Stabilizer.
• "USM" stands for Ultrasonic Motor.
Features
1. The Image Stabilizer gives the equivalent
effect of a shutter speed four stops faster*.
The lens also has a second image stabilizer
mode that is optimized for following shots of
moving subjects.
2. The lens features outstanding image quality
through the use of fluorite, super UD, and UD
lens elements.
3. Ultrasonic motor (USM) for quick and quiet
autofocusing.
4. Manual focusing is available after the subject
comes into focus in autofocus mode (ONE
SHOT AF).
5. The AF Stop button for stopping the AF
operation at anytime.
6. Focus preset enables you to focus instantly at
a preset distance.
7. A truly round aperture hole results in a nicer
background blur.

aSafety Precautions
aSafety Precautions
• Do not look at the sun or a bright light source through the
lens or camera. Doing so could result in loss of vision. Looking
at the sun directly through the lens is especially hazardous.
• Do not point the lens or camera at the sun or photograph
it. This is because the lens concentrates the sun’s rays even
when the sun is outside the image area or when shooting
with backlight, which could cause malfunction or fire.
•Whether it is attached to the camera or not, do not
leave the lens under the sun without the lens cap
attached. This is to prevent the lens from concentrating
the sun’s rays, which could cause a fire.
•Do not stand on the lens case. Falling off the case
could result in injury.
•Do not stack lens cases. A falling lens case could
cause an injury.
Handling Cautions
• If the lens is taken from a cold environment into a
warm one, condensation may develop on the lens
surface and internal parts. To prevent condensation in
this case, first put the lens into an airtight plastic bag before
taking it from a cold to warm environment.Then take out
the lens after it has warmed gradually. Do the same when
taking the lens from a warm environment into a cold one.
•Do not leave the lens in excessive heat such as in a
car in direct sunlight. High temperatures can cause
the lens to malfunction.

4. Infinity Compensation Mark
Infinity compensation mark
Distance 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.
For accurate manual focusing on subjects at
infinity distance, look through the viewfinder while
rotating the focusing ring.

9.Tips on Using the Image Stabilizer
The image stabilizer in this lens is effective for hand-held shots or when using a monopod under the
following conditions.
●MODE 1 ●MODE 2
•In moderately dark areas such as evening
scenes.
•In locations where flash photography is
prohibited such as live performances in
theaters.
•In situations where your footing is uncertain.
•In situations where fast shutter settings cannot
be used.
•When panning subjects in motion.
COPY

ENG-11
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
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 shoot while riding on a bumpy road.
•You move the camera dramatically for a
panning shot in Mode 1.
•You shoot using techniques other than
following 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
button. 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 II E/50/50E, REBEL2000/300, 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.
•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 or EF25 ll.
•With Extender EF1.4X II/EF2X II attached to the
lens, the Image Stabilizer will work with the
following cameras:
EOS-1Ds Mark III, EOS-1Ds Mark II, EOS-1Ds, EOS-1D Mark
lll, EOS-1D Mark II N, EOS-1D Mark II, EOS-1D, EOS 40D,
