ENG-1
Thank you for purchasing a Canon product.
Dedicated to EOS cameras, the Canon EF70-
300mm f/4-5.6 IS USM lens is a high-
performance telephoto zoom 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 three stops faster*.
The lens also has a second image stabilizer
mode that is optimized for following shots of
moving subjects.
2. UD lens elements for excellent imaging
performance.
3. The zoom ring can be fixed to keep the lens
at the shortest point.
4. Ultrasonic motor (USM) for quick and quiet
autofocusing.
5. A truly round aperture hole results in a nicer
background blur.
*Based on [1/focal length] second. Generally, it requires
a shutter speed [1/focal length] second or faster to
prevent camera shake.

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.
•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.
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.
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

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 installed and used in accordance with the
instructions, may cause harmful interference to radio
communications.
However, there is no guarantee that interference will not occur in
a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be
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.

2. Setting the Focus Mode
¡Do not touch the rotating parts of the lens while
autofocus is active.
¡Do not adjust focus manually when the focus
mode switch is set to AF.
To shoot in autofocus (AF) mode, set the focus
mode switch to AF.
To use only manual focusing (MF), set the focus
mode switch to MF, and focus by turning the
focusing ring.
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
electrical 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
K index of the dust cap as shown
in the diagram, and turn clockwise. To remove it,
reverse the order.

4. 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.
3. Hood (Sold separately)
¡The front end of the lens rotates, so hold it when
attaching the hood.
¡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.
The ET-65B hood can keep unwanted light out of
the lens, and also protects the front of the lens
from rain, snow, and dust.
Attach and align the hood to the hood mount on
the front of the lens, and turn the hood as shown
by the arrow to secure it.
The hood can be reverse-mounted on the lens
for storage.

5. Fixing the Zoom Ring
The zoom ring can be fixed to keep the lens at the shortest point. This function is convenient for
carrying a camera on a strap because it prevents the lens from extending.
1Turn the zoom ring to
the widest position
(70mm).
2Slide the zoom ring
lock lever in the
direction indicated by
the arrow.
¡To release the zoom ring,
slide the zoom ring lock
lever in the direction
opposite to the arrow.
The zoom ring can only be locked at maximum wide angle.

6. Image Stabilizer
You can use the image stabilizer in AF or MF mode.
1Set the STABILIZER
switch to .
¡If you are not going to
use the image stabilizer
function, set the switch to
.
2Select the stabilizer
mode.
¡MODE 1: Corrects
vibrations in all
directions. It is mainly
effective for shooting still
subjects.
¡MODE 2: It compensates
for vertical camera shake
during following shots in
a horizontal direction,
and compensates for
horizontal camera shake
during following shots in
a vertical direction.
3When you press the
shutter button halfway,
the Image Stabilizer
will start operating.
¡Make sure the image in
the viewfinder is stable,
then press the shutter
button the rest of the way
down to take the picture.

7. 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.
¡When panning subjects in motion.

Tips on Using the Image Stabilizer
¡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 an
Extension Tube EF12 ll or EF25 ll.
¡Pictures may look distorted after being
taken depending on the camera, but this
doesn't 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.
¡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, 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.
