a Safety Precautions  
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.  
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 ca
attached. This is to prevent the lens from

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:  
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.

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.  
• After detaching the lens, place the lens with t
rear end up to prevent the lens surface and  
electrical contacts from getting scratchd.  
• If the contacts get soiled, scratched, or ave  
fingerprints on them, corrosion or faulty  
connections can result. The camera and lens  
may not operate properly.  
After autofocusing in ONE SHOT AF mode, focus  
manually by pressing the shutter button halfway  
and turning the focusing ring. (Full-time manual  
focus)  
• 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.

Be sure to finish zooming before focusing.  
Changing the zoom ring after focusing can affect  
the focus.  
If the current focusing distance is not within the  
focusing distance range you switch to, the lens  
focusing may first stop at the start or end of the  
focusing range. This is normal and not a  
malfunction. Just press the shutter button halfway  
again to resume normal autofocusing.

Some EOS cameras cannot use infrared film. See  
the instructions for your EOS camera.  
For accurate manual focusing on subjects at  
infinity distance, look through the viewfinder 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.  
• Be sure to observe the manufacturer’s  
instructions when using infrared film.  
• Use a red filter when you take the picture.

• If you need a polarizing filter, use the Canon  
Circular Polarizing Filter (67mm).  
To adjust the polarizing filter, first remove the  
lens hood.  
The ET-74 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
the front of the lens, and turn the hood as sho
by the arrow to secure it.  
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.

9. Using the Tripod Mount  
(Sold separately)  
Adjusting the Revolving Mount  
This lens can be used with the A II (W) 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.

With the collar open,  
remove the tripod mount.  
To install, while pulling the  
locking knob, bring the collar  
to the original position, and  
tighten the locking knob  
securely.

EOS-1D, EOS-1V/HS, EOS-3 camera, autofocusing with the center focusing point is possible.  
• Only one Extender can be attached to the lens and camera.  
• If you use an Extender on the lens mounted on a EOS A2/A2E/5, set the exposure  
compensation to -1/2 stop for the EF1.4X II or -1 stop for the EF2X II.  
• Autofocusing is still enabled with Extender EF1.4X II attached.  
• When an Extender is attached, the AF speed will become slower by design to retain proper  
AF control.
