Instruction

ENG-1
Thank you for purchasing a Canon USM lens.
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.
The Image Stabilizer helps to prevent blurred
shots during hand-held shooting at slow
shutter speeds.
¡“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.
2. UD lens elements for excellent imaging
performance.
3. The Image Stabilizer mode is available
according to shooting conditions.
4. The zoom ring can be fixed at the widest
position.
5. USM for fast, quiet focusing.
6. A truly round aperture hole results in a nicer
background blur.

aSafety Precautions
aSafety Precautions
1. 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.
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.

2. Setting the Focus Mode
¡Unless the focus mode switch is set to MF, you
cannot focus manually.
¡Do not touch the focusing ring or rotating parts
of the lens while autofocus is in action.
To shoot in autofocus mode, set the focus mode
switch to AF.
To use only manual focusing, 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 reduces annoying flare and
also protects the front of the lens from rain,
snow, dust, etc.
To attach the hood, connect the hood’s tabs to
the hood attachment tabs on the front end of the
lens, then turn the hood clockwise 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 at the widest position. 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
.
2Selecting the Image
Stabilizer mode.
¡Use MODE 1 for normal
photography.
MODE 1 provides image
stabilization in all
directions.
¡Use MODE 2 for
continuous shots of
moving subjects.
MODE 2 provides image
stabilization only in the
direction of camera
movement.
3Press the shutter
button halfway to
verify the effect of the
image stabilizer.
¡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 is effective particularly for hand-held shots under the following conditions.
¡Dimly lit scenes, such as at dusk or indoors
¡Locations such as art galleries or theater
stages where flash photography is forbidden
¡Situations in which your footing is uncertain
¡If you are taking continuous shots of a moving
subject
¡If you are tracking an erratically moving
subject
* MODE 1 should be used in all other situations.

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.
¡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 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.
¡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.
