Features
1.  The Image Stabilizer gives the equivalent effect 
of a shutter speed four stops* faster. 
Also, a third Image Stabilizer mode effective for 
shooting irregularly moving subjects.
2.  Use of fluorite lens elements giving superior 
definition.
3.  SWC (Subwavelength Structure Coating) 
reduces flare and ghosting.
4.  Using a fluorine coating on the foremost and 
rearmost lens surfaces allows adhered dirt to be 
removed more easily than before.
5.  Ultrasonic motor (USM) for fast, quiet autofocus.
6.  Manual focusing is available after the subject 
comes into focus in autofocus mode (ONE 
SHOT AF).
7.   An AF stop button to pause autofocus whenever 
desired. 8.
 A power focus mode enables smooth focus 
change.
9.  A focus preset function for advance storage 
of focusing positions in memory to allow 
instantaneous focusing.
10.  Circular aperture for producing beautiful 
softfocus images.
11.  Can be used with EF1.4× III/EF2× III extenders.
12.  Attachment slot provided for wire-type security 
lock, located under the cover for the orientation 
locking knob.
13.  Tight seal structure ensures excellent dustproof 
and drip-proof performance.
14.  Designed for lighter weight with parts made of 
magnesium alloy.
*  Based on [1/focal length] second.
  Generally, it requires a shutter speed [1/focal length] 
second or faster to prevent camera shake.

 Safety Precautions
 Safety Precautions
Do not look at the sun or a bright light source 
OO
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 
OO
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 
OO
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.
When the lens is mounted on a camera, be sure to also 
OO
hold the camera by the lens, including when mounting 
on a tripod. Only holding by the camera could result in 
scratches on the camera body or the lens itself. The lens 
may also detach from its mount and fall, causing injury.
Do not use a strap attached to the camera. The mount 
OO
may break, resulting in the lens falling off and causing 
injury or in scratches on the camera. Be sure to use the 
camera with a dedicated strap attached correctly to the 
strap mount on the lens.
Do not stand on top of the lens case. You may fall and 
OO
injure yourself.
Do not pile lens cases on top of one another as they 
OO
may fall and cause injury.
Conventions used in this instruction
  Warning to prevent lens or camera malfunction 
or damage.
  Supplementary notes on using the lens and 
taking pictures.
Handling Cautions
If the lens is taken from a cold environment into a 
OO
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 
OO
in direct sunlight.  High temperatures can cause the 
lens to malfunction.

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 
dust- and water-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.
Attaching the strap
Thread the end of the strap through the strap 
mount on the lens and then back through the 
clasp on the strap. Pull the strap tight and check 
that there is no slack in the clasp.
After detaching the lens, place the lens with 
OO
the rear end up to prevent the lens surface and 
contacts from getting scratched.
If the contacts get soiled, scratched, or have 
OO
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 
OO
them, clean them with a soft cloth.
If you remove the lens, cover it with the dust cap. 
OO
To attach it properly, align the lens mount index 
and the   index of the dust cap as shown in 
the diagram, and turn clockwise. To remove it, 
reverse the order.

To shoot in autofocus (AF) mode, set the focus 
mode switch to AF.
To shoot in manual focus (MF) mode, set the 
focus mode switch to MF, and focus by turning 
the focusing ring. The focusing ring always 
works, regardless of the focus mode.
To shoot in power focus (PF) mode, set the 
focus mode switch to PF when the focus preset 
switch (p. 8) is at OFF.
Operating the playback ring enables focus 
change at a set speed. This is a useful feature 
for changing focus when shooting movies.
You can set the focusing distance range with a 
switch. By setting a suitable focusing distance 
range, the actual autofocusing time will be 
shorter.

4. AF Stop Button
The AF stop function also works in AI Servo AF 
mode.
Angle positioning of the AF stop button is 
adjustable by a Canon Service Center at cost.

OO
set to the AI Servo AF mode and continuous 
shooting, AF will not resume even after you 
let go of the AF stop button. Press the shutter 
release button halfway to resume AF.
With the EOS A2/A2E/5 and 10S/10 set to the

Focus Preset
When turning the playback ring, keep your finger 
OO
away from the shutter button. In One-Shot AF 
mode, the exposure will be locked when you 
press the shutter button halfway and focus is 
achieved. So if you press the shutter button 
halfway while turning the playback ring, the 
exposure may not be correct.
When not using the focus preset, set the switch 
OO
to OFF.
The focus preset function will not work while a 
OO
Live View image is displayed on the camera.*
By turning the playback ring to the left or right, 
the focus shifts as far as the preset distance.
Focus will shift freely released of AF focusing 
while the playback ring is still turned.
If the focus preset switch was set to 
OO, the beeper 
will sound twice.
Setting the focus mode switch to power focus 
(PF) when using the lens with the EOS-1D X 
or EOS 5D Mark III enables focus change at a 
slow set speed during movie shooting. Also, you 
can make a 2-step change in focus shift speed 
depending on the angle that the playback ring is 
rotated to.
In the following cases, the focusing distance scale 
(p. 14) will move slightly. It will not affect the image.
• When you press the focus preset button.
• When you turn the playback ring.
