							ENG-1
Dedicated to EOS cameras, the Canon EF70-
300mm f/4-5.6L 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.
4. Ultrasonic motor (USM) for quick and quiet
autofocusing.
5. Manual focusing is available after the subject comes into focus in autofocus mode (ONE
SHOT AF).
6. The zoom ring can be fixed to keep the lens at the shortest point.
7. A truly round aperture hole results in a nicer background blur.
8. Tight seal structure ensures excellent dust- proof and drip-proof performance.
*Based on [1/focal length] second. Generally, it requires
a shutter speed [1/focal length] second or faster to
prevent camera shake.
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. UD lens elements for excellent imaging performance.
3. A fluorine coating has been applied to the lens’s front and rear lens elements which
allows dust to be wiped from the outside of the
lens more easily compared with previous
lenses.
Thank you for purchasing a Canon product.

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.
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
wa rm  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
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 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.

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 
Kindex of the dust cap as shown
in the diagram, and turn clockwise. To remove it,
reverse the order.
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
rub ber ring becomes worn, it is replaceable by a
Canon Service Center at cost.

3. Zooming
To   zoom, turn the zoom ring.
Be sure to finish zooming before focusing.
Zooming after focusing can affect the focus.
Especially for shooting distances shorter than 3 m
/ 9.8 ft., zooming to another focal length will
greatly change the focus.
2. Setting the Focus
Mode
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
f ocusing 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

4. Hood
The ET-73B 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 as shown by the arrow until the lens red dot is aligned with the hoods stop
position mark.
The hood can be reverse-mounted on the lens for storage.
•P art 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
gr asp the rim of the hood to turn it.

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.
5. Fixing the Zoom Ring
Slide the zoom ring lock
lever in the direction
indicated by the arrow.
•T
o release the zoom ring, slide
the zoom ring lock lever in the
direction opposite to the arrow.

ou can use the image stabilizer in AF or MF mode.
6. Image Stabilizer Settings
Select the stabilizer mode.
• MODE 1: Corrects vibrations
in all directions. It is mainly
effective for shooting still
subjects.
• MODE 2: It compensates for
ver tical camera shake during
f ollowing shots in a horizontal
direction, and compensates for
horizontal camera shake
during following shots in a
ver tical direction.
When 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.
Set the STABILIZER switch
to .
•If you are not going to use the
image stabilizer function, set
the switch to         .
