Safety Precautions  
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 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.  
The F11-24mm f/4L USM features a large diameter  
froens element. Please be careful because this  
arge ont section will extend past the bottom of some  
cameras.  
Do not leave the lens in excessive heat such as in a car  
in direct sunlight. High temperatures can cause the  
lens to malfunction.  
Usage Precautions  
Conventions used in this instruction  
When using this lens, please check the Canon webse  
for the latest camera firmware. If the camera’s fimware  
is not the latest version, be sure to update to the latest  
firmware.  
Warning to prevent lens or camera malfunction  
or damage.  
For details on updating firmware, please check the  
Canon website.  
Supplementary notes on using the lens and  
taking pictures.  
ENG-2  
 
Precautions for Shooting  
If dirt or dust adheres to the surface of the front lens element, it can easily appear in images due to the  
lens’s short focal length. In order to avoid this, please remove dirt or dust from the surface of the front lens  
element by using a commercially available air dust blower.  
Since this lens has a wide angle of view, light from bright light sources, such as the sun, can easily enter  
the image area. Please do not look at bright light sources using the camera’s viewfinder.  
Similarly, flare and ghost will occur when bright light sources appear in the image area, depending on  
shooting conditions. In order to prevent flare and ghost, we suggest shooting places such as shaded are  
as so that bright light does not enter the lens.

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.  
CAN ICES-3 (B) / NMB-3 (B)  
This equipment has been tested and found to comply with  
the limits for a class B digital device, pursuant to part 15  
of the FCC Rules. These limits are designed to provide  
reasonable protection against harmful interference in a  
residential installation. This equipment generates, uses and  
can radiate radio frequency energy and, if not installed
used in accordance with the instructions, may cause ha
interference to radio communications.  
However, there is no guarantee that interference ill not  
occur in a particular installation. If this equipment des  
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:  
• Reorient or relocate the receiving antenna.  
• Increase the separation between the equipment and  
receiver.  
• Connect the equipment into an outlet on a circuit different  
from that to which the receiver is connected.  
• Consult the dealer or an experienced radio/TV technician  
for help.

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.  
Please be careful when laying the lens  
seways. The lens may roll and fall, resulting  
in njury.  
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.  
ENG-6  
 
2. Setting the Focus Mode 3. Zooming  
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 turnin
the focusing ring.  
To zoom, rotate the zoom ring.  
Also, te minimum focusing distance of the lens  
nges depending on focal length.

After autofocusing in ONE SHOT AF mode, focus  
manually by pressing the shutter button halfway  
and turning the focusing ring. (Full-time manual  
focus)  
Be sure to finish zooming before focusing.  
Zooming after focusing can affect the focus.  
Zooming in causes the front lens assembly to  
extend along the lens’s optical axis. This adds  
to the weight of the lens assembly, so pointing  
it up or down when zooming in may increase or  
decrease the torque felt in the zoom ring.

4. InfinityꢀCompensationꢀ 5. Infrared Index  
Mark  
Infinity compensation  
mark  
The inared index corrects the focus setting  
Distance index  
when ing monochrome infrared film. Focus on  
subjct manually, then adjust the distance  
stting by moving the focusing ring to the  
corresponding infrared index mark.  
To compensate for shifting of the infinity focus  
point that results from changes in temperatur
there is a margin at the infinity () positon.  
The infinity position at normal temperatre is the  
point at which the vertical line of the distance  
scale L mark is aligned with the distance index.  
Some EOS cameras cannot use infrared film. See  
the instructions for your EOS camera.  
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.  
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.  
* For cameras with Live View shooting capability.

6. Lens Cap  
7. Filter (Sold separately)  
Lock knobs  
The lens cap can be attached by pinching the  
lock knobs and vertically aligning the lens cap  
with the lens hood as shown in the diagram.  
There a gelatin filter holder at the rear of the  
lens. Ct the gelatin filter to fit within the white  
es. Then insert the gelatin filter into the filter  
hlder.  
The recessed sections of the lens hood tht the  
cap locks on to are located at the front insde edge  
of the top and bottom petals.  
The lens’s rear lens group moves back toward the  
rear of the lens (camera side) the most when the  
lens is set to the wide end. Therefore, in order to  
prevent the rear lens element from making contact  
with a filter (when installed), we recommend using  
a filter only if the zoom ring is not set to the wide  
end.
