The Canon EF28-300mm f/3.5-5.6L IS USM
lens is a powerful high-performance zoom
lens for EOS cameras equipped with an
Image Stabilizer, and covering a wide range
of focal lengths from wide angle to telephoto.
•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. Aspheric and UD lens elements for truly exceptional imaging capability.
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. A truly round aperture hole results in a nicer background blur.
6. Adjustable zoom ring touch lets you lock at any focal length.
7. 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.
Thank you for purchasing a Canon product.

a Safety Precautions
aPrecautions for using the lens with the
EOS-1N RS
When shooting with this lens attached to an EOS-1N
RS, use -2/3 or -1/2 step exposure compensation.
a Safety 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.

See your camera’s instructions for details on
mounting and detaching the lens.
1. 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.
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.

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.
2. Setting 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
f ocus)
3. Switching the Focusing
Distance Range
You can set the focusing distance range to 
0.7 m/2.3 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.
If you autofocus outside the set focusing distance
r ange, the lens may stop focusing at the start of
the focusing range; however, this is not a
malfunction. Press the shutter release button
halfway again.

5.Adjusting Zooming Resistance
You can adjust the zooming “touch” (resistance)
as needed by holding the focusing ring in place
and turning the adjustment ring.
Tu rn  the adjustment ring towards the word
SMOOTH to reduce the zooming touch, or towards
TIGHT to increase it. To lock the zoom ring in
place, turn the adjustment ring towards TIGHT until
it stops.
4. Zooming
Move the zoom ring forward or backward to
z oom.
• Be sure to finish zooming before focusing.
Zooming after focusing can affect the focus.
•T o prevent unintended zooming when not
shooting, be careful not to set the zooming touch
too loose.

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.
6. Image Stabilizer Settings
You can use the image stabilizer in AF or MF mode.
Set the STABILIZER switch
to .
• If you are not going to use the
image stabilizer function, set
the switch to  .
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.

7. Tips on Using the Image Stabilizer
•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.
•I n situations where fast shutter settings cannot
be used.
The image stabilizer in this lens is effective for hand-held shots under the following conditions.
•When panning subjects in motion.
● MODE 1 ●MODE 2

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 doesnt 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
e xposures). 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:
•Y ou shoot while riding on a bumpy road.
•Y ou move the camera dramatically for a panning
shot in Mode 1.
•Y ou 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.
•W ith the EOS-1V/HS, 3, ELAN 7E/ELAN 7/30/33,
ELAN 7NE/ELAN 7N/30V/33V, ELAN II/ELAN
IIE/50/50E, REBEL 2000/300, IX, and D30, the
Image Stabilizer will not work during self-timer
operation.
