EF70-200mm F2.8L IS USM  
						

							
ENG-1
The Canon EF 70-200mm f/2.8L IS USM is a
high-performance, telephoto zoom lens
dedicated to Canon EOS cameras. It is equipped
with an Image Stabilizer to help preventing blurred
shots due to camera shake during slow shutter
speeds.
In the lens name, IS stands for Image
Stabilizer, and USM for Ultrasonic Motor.
aHandling 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. Features
1. The four UD elements help capture very sharp
and clear pictures with outstanding image
delineation.
2. The Image Stabilizer gives the equivalent effect of a shutter speed three stops faster.
3. Ultrasonic motor (USM) for fast, quiet focusing.
4. Manual focusing enabled during AF (autofocusing).
5. A truly round aperture hole results in a nicer background blur.
6. Compatible with Extenders.
7. Sealed construction for higher resistance against dust and moisture.

set out in the interference-causing equipment standard
entitled “Digital Apparatus”, ICES-003 of the Industry
Canada.
N118
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions: (1)
This device may not cause harmful interference, and (2)
this device must accept any interference received,

ENG-4 See your camera’s instructions for details on
mounting and detaching the lens.
•After detaching the lens, put it down with the
contacts upwards, to avoid damaging the
contacts or lens surface.
• If the contacts are dirty, scratched, or soiled with
fingerprints, etc., corrosion or a faulty
connection or operation may result.
•
Always attach the dust cap to the lens whenever it
is not mounted on the camera. To attach the dust
cap, align the mark on the dust cap with the mark
on the lens and turn the dust cap clockwise. To
remove the dust cap, turn it counterclockwise.

1. Mounting and Detaching the Lens
The lens mount has a rubber ring for enhanced
w ater- and dust-resistance. The rubber ring may
cause slight abrasions around the cameras lens
mount, but this will not cause any problems. If the
ru bber ring becomes worn, it is replaceable by a
Canon Service Center at cost.  
						

							
ENG-5
•Before switching the focusing distance range,
turn the focusing ring so that the current
focusing distance is within the focusing distance
r ange you want to switch to.
• If the current focusing distance is not within the
focusing distance range you switch to, the lens
f ocusing may first stop at the start of the
f ocusing range. This is normal and not a
malfunction. Just press the shutter button
halfway again to resume normal autofocusing.
Y ou can set the focusing distance range to 
1.4 m/4.6 ft. to infinity or 2.5 m/8.2 ft. to infinity.
By setting the suitable focusing distance range,
the actual autofocusing time can be shorter.

3.Switching the Focusing
Distance Range
If you are going to take pictures using autofocus,
set the focus mode switch to  .
To  focus manually, set the focus mode switch to 
and turn the focusing ring.

2. Setting the Focus Mode

5. Focusing Ring
The focusing ring can be used at any time
regardless of the focus mode.
•After autofocusing with the camera in ONE SHOT AF
mode, you can adjust the focus by keeping the shutter
button pressed halfway and turning the focusing ring.

4. Zooming
To  z oom, turn the zoom ring.
• Be sure to finish zooming before focusing.
Zooming after focusing can affect the focus.
•F or flash pictures, use an external, EOS-
dedicated Speedlite instead of the cameras
b uilt-in flash. The long lens may partially
obstruct the light of the built-in flash.  
						

							
ENG-7
The image stabilizer function can be used in both  and  focus modes.

6. Image Stabilizer Settings

Select the stabilizer mode.
•Select MODE 1 for standard
photography. MODE 1 corrects
all vibrations no matter
whether the camera is being
held horizontally, vertically, or
at an angle.
•T o pan a moving subject,
select MODE 2.
MODE 2 corrects vibrations
and shaking only in the
direction at right angles to the
camera’s panning movement.

Press the shutter button
down halfway to check the
stabilization.
• Make sure the image in the
viewfinder is stable, then press
the shutter button all the way
down to take pictures.

Set the STABILIZER switch
to .
•If you are not going to use the
image stabilizer function, set
the switch to         .

7. Tips on Using the Image Stabilizer

qIn semi-darkened areas such as indoors or
outdoors at night.
w In locations where flash photography is
prohibited, such as art museums and theater
stages.
e In situations where fast shutter settings
cannot be used.
r In situations where your footing is uncertain. q
When panning subjects in motion.
w When following subjects that are moving
erratically.
*W e recommend MODE 1 for all other situations.
●MODE 1 ●MODE 2

The image stabilizer function is particularly effective for hand-held photography in the following
situations:

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 move the camera for a panned shot.
• You shoot while riding on a bumpy road.
• Compared to using a normal non-IS lens, fewer
shots can be taken when you use an Image
Stabilizer lens because more power is
consumed.
• 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.
•W ith the EOS-1V/HS, 3, 30/33/Elan7/7E,
30V/33V/Elan7N/7NE, Elan ll/Elan ll E/50/50 E,
300/Rebel2000, IX, and D30, the Image
Stabilizer will not work during self-timer
operation.
• 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 the EF12 II or EF25
II Extension Tube, and the EF1.4X II or EF2X II
Extender.
• 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.
