English Instructions
Thank you for purchasing a Canon product.
Canon EF28-135mm f/3.5-5.6 IS USM is a high-
performance lens developed for EOS cameras that
incorporates an Image Stabilizer function.
●“IS” stands for Image Stabilizer.
● “USM” stands for Ultrasonic Motor.Features1. The Image Stabilizer gives the equivalent effect of a
shutter speed two stops* faster.
2. High-magnification zoom from 28 mm wide-angle to 135 mm telephoto.
3. Ultrasonic motor (USM) for fast, quiet autofocus.
4. Manual focusing is available after the subject comes into focus in autofocus mode (ONE SHOT AF).
5. Great close-ups at 0.5 m/1.6 ft at all focal lengths.
* Based on [1/focal length] second. 
Generally, it requires a shutter speed [1/focal length]
second or faster to prevent camera shake.
Conventions used in this instruction
Warning to prevent lens or camera
malfunction or damage.
Supplementary notes on using the lens and
taking pictures.
a Handling CautionsIf 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.

determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of
the following measures:
•Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
•
Consult the dealer or an experienced radio/TV technician for help.
This Class B digital apparatus complies with Canadian ICES-003.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, including interference that may cause
undesired operation.
Do not make any changes or modifications to the equipment
unless otherwise specified in the instructions. If such changes or
modifications should be made, you could be required to stop
operation of the equipment.
This equipment has been tested and found to comply with the limits
for a class B digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not
a Safety Precautions1. 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.
2. 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.

1. Mounting and Detaching the Lens
See your camera’s instructions for details on mounting and detaching the lens.
•After detaching the lens, place the lens with the rear end up to
prevent the lens surface and contacts from getting scratched.
• If the contacts get soiled, scratched, or have fingerprints on them,
corrosion or faulty connections can result. The camera and lens
may not operate properly. 
• If the contacts get soiled or have fingerprints on them, clean them
with a soft cloth.
• If you remove the lens, cover it with the dust cap. To attach it properly, align the lens mount index and the  
index of the
dust cap, and turn clockwise. To remove it, reverse the order.

3. Setting the Focus Mode
To  shoot in autofocus (AF) mode, set the focus mode switch to AF.
To   shoot in manual focus (MF) mode, set the focus mode switch to MF, and
focus by turning the focusing ring. The focusing ring always works,
regardless of the focus mode.
After autofocusing in ONE SHOT AF mode, focus manually by pressing the
shutter button halfway and turning the focusing ring. (Full-time manual\
 focus)
2. Zooming
To   zoom, turn the lens’ zoom ring.
Be sure to finish zooming before focusing. Changing the zoom ring after
focusing can affect the focus.

operate the AF, the Image Stabilizer will operate when you press the newly
assigned AF  button.

ou can use the image stabilizer in AF or MF mode.
1. Set the STABILIZER switch to ON. • If you are not going to use the image stabilizer function, set the switc\
hto OFF.
2. When you press the shutter button halfway, the Image Stabilizer will start operating.
• Make sure the image in the viewfinder is stable, press the shutterbutton the rest of the way down to take the picture.

5. Tips on Using the Image Stabilizer
The image stabilizer in this lens is effective for hand-held shots under the following conditions.
•In semi-darkened areas such as indoors or outdoors at night.
• In locations where flash photography is prohibited, such as art museums \
and theater stages.
• In situations where your footing is uncertain.
• In situations where fast shutter settings cannot be used.
• The Image Stabilizer cannot compensate for a blurred shot caused by a su\
bject that moved.
• Set the STABILIZER switch to OFF when using the camera on a tripod. If the switch \
is set to ON, the Image Stabilizer may
introduce errors.
• Set the STABILIZER switch to OFF when you are taking pictures using the Bulb setti\
ng (long exposures). If the
STABILIZER switch is set to ON, the image stabilizer function may introduc\
e errors.
• The Image Stabilizer might not be fully effective in the following cases:
•Y ou move the camera for a panned shot.
•Y ou 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 finge\
r 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, ELAN 7E/ELAN 7/30/33, ELAN 7NE/ELAN 7N/30V/33V, ELAN II/ELAN II E/50/50E, REBEL
2000/300, IX, IX Lite/IX7, and D30, the Image Stabilizer will not work d\
uring self-timer operation.
• 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 a\
n extension tube EF12 II or EF25 II.
• Depending on the camera there may be image shake, such as after releasin\
g the shutter. However, this does not 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.

6. Infinity Compensation Mark
To  compensate for shifting of the infinity focus point that results from ch\
anges 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.
7. Infrared Index
The infrared index corrects the focus setting when using monochrome infr\
ared
film. 
Focus on the subject in MF, then adjust the distance setting by moving the
focusing ring to the corresponding infrared index mark.
For accurate focusing in MF on subjects at infinity distance, look throu\
gh the
viewfinder while rotating the focusing ring.
• The infrared index position is based on a wavelength of 800 nm.
• Be sure to observe the manufacturer’s instructions when using infrared film.
• Use a red filter also when you take the picture.
Some EOS cameras cannot use infrared film. See the instructions for your\
 EOS
camera.

8. Hood and Filters
Hood (Sold Separately)The EW-78B II lens hood can keep unwanted light out of the lens, and also
protects the lens from rain, snow, and dust. To attach the hood, align the
hood’s attachment position mark with the red dot on the front of the lens,
then turn the hood in the direction of the arrow until the lens’s red dot is
aligned with the hood’s stop position mark. The hood can be reverse-
mounted on the lens for storage.
•Part of the picture may be blocked if the hood is not attached properly.
• When attaching or detaching the hood, grasp the base of the hood to turn\
 it.
To   prevent deformation, do not grasp the rim of the hood to turn it.
