 Safety Precautions
 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.
●● When the lens is mounted on a camera, be sure to 
also 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 
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 
injure yourself.
●● Do not pile lens cases on top of one another as they 
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 
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.

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 
the rear end up to prevent the lens surface and 
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   index of the dust cap as shown 
in the diagram, and turn clockwise. To remove it, 
reverse the order.

2. Setting the Focus Mode3.  Switching the Focusing 
Distance Range
After autofocusing in ONE SHOT AF mode, focus 
manually by pressing the shutter button halfway 
and turning the focusing ring. (Full-time manual 
focus)
To shoot in autofocus (AF) mode, set the focus 
mode switch to AF.
To shoot in manual focus (MF) mode, set the

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.
Ranges
1. FULL (2 m/6.56 ft. - ∞)
2. 2 m/6.56 ft. - 6 m/19.69 ft.
3. 6 m/19.69 ft. - ∞

Focus Preset
●●After the focus distance has been preset, turning 
the playback ring to a different zoom position or 
changing the internal extender setting will result 
in an out of focus picture. Therefore, use the 
focus preset function after zooming is completed 
and the internal extender has been set.
●● The focus preset function will not operate for a 
few seconds after setting the internal extender 
(the amount of time varies depending on the 
camera used).
●● After setting the internal extender, please press 
the shutter button halfway before setting or using 
the focus preset.
●● When turning the playback ring, keep your finger 
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 
to OFF.
●● The focus preset function will not work while a 
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 , the beeper 
will sound twice.
Setting the focus mode switch to power focus 
(PF) when using the lens with the EOS-1D X, 
EOS 5D Mark III, or EOS REBEL T4i/650D 
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.
* Not applicable to the EOS-1D X, EOS 5D Mark III, or 
EOS  REBEL T4i/650D
In the following cases, the focusing distance scale 
(p. 18) will move slightly. It will not affect the image.
• When you press the focus preset button.
• When you turn the playback ring.
