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.  
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.  
• 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.

1. Mounting and Detaching the Lens  
See your camera’s instructions for details on  
mounting and detaching the lens.  
The lens mount has a rubber ring for enhanced  
water- and dust-resistance. The rubber ring may  
cause slight abrasions around the camera's lens  
mount, but this will not cause any problems. If the  
rubber ring becomes worn, it is replaceable by a  
Canon Service Center at cost.  
• 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.  
ENG-4  
 
2. Setting the Focus  
Mode  
3. Zooming  
To zoom, turn the zoom ring.  
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. The focusing ring always works,  
regardless of the focus mode.  
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.  
After autofocusing in ONE SHOT AF mode, focus  
manually by pressing the shutter button halfway  
and turning the focusing ring. (Full-time manual  
focus)  
ENG-5  
 
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 poson mark with the red dot on the front of the  
lens, then turn the hood as shown by the arrow il the lens' 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.  
ENG-6  
 
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.  
Turn the zm ing to the  
widest pon (70mm).  
Slide 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.

effecive 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.  
• If you are not going to use the  
image stabilizer function, set

7. Tips on Using the Image Stabilizer  
The image stabilizer in this lens is effective for hand-held shots under the following conditions.  
MODE 1  
MODE 2  
• In semi-darkened areas such as indoors or  
outdoors at night.  
• When panning subjects in motion.  
• 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.  
ENG-9  
 
Tips on Using the Image Stabilizer  
• The Image Stabilizer cannot compensate for a  
blurred shot caused by a subject that moved.  
• Using a tripod also stabilizes the image.  
However, depending on the kind of tripod and  
shooting conditions, sometimes it may be better  
to turn off the Image Stabilizer function.  
• Even with a monopod, the Image Stabilizer will  
be as effective as during hand-held shooting.  
However, depending on the shooting  
environment, the Image Stabilizer effect may be  
less effective.  
• 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.  
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 powr  
than normal shooting, so fewer shots can be  
taken if you use the function.  
• 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 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, 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.  
ENG-10  
 
8. Infinity Compensation Mark  
9. Infrared Index  
Infinity compensation mark  
Distance index  
To compensate for shifting of the infinity focus  
point that results from changes 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.  
The infrared index corrects the focus setting when using  
monohrome infrared film. Focus on the subject  
nually, then adjust the distance setting by moving the  
focusing ring to the corresponding infrared index mark.  
Some EOS cameras cannot use infrared film. See  
the instructions for your EOS camera.  
For accurate manual focusing of subjects at  
infinity, look through the viewfinder or look at the  
magnified image* on the LCD screen while  
rotating the focusing ring.  
• The infrared index position is based on a  
wavelength of 800 nm.  
The compensation amount differs depending on  
the focal length. Use the indicated focal length as  
a guide when setting the compensation amount.  
* For cameras with Live View shooting capability.  
• Be sure to observe the manufacturer’s  
instructions when using infrared film.  
• Use a red filter when you take the picture.  
ENG-11  
 
10. Using the Tripod Mount  
(Sold separately)  
Adjusting the Revolving Mount  
This lens can be used with the C (W II) tripod mount ring, sold separately.  
You can loosen the orientation lock-knob on the tripod mount to allow it to rotate as needed to fit a  
particular camera model for switching between vertical and horizontal positions.  
Detaching  
Use the following procedures to remove and attach the tripod mount.  
Turn the locking knob  
counterclockwise until it  
becomes loose (about 3 turns),  
and pull the knob in the direction  
of the arrow to release the collar.  
With the collar open,  
remove the tripod mount.  
To install, while pulling the  
locking knob, bring the collar  
to the original position, and
