Thank you for purchasing a Canon product.The Canon EF-M18-55mm f/3.5-5.6 IS STM lens is a 3x 
standard zoom lens developed for interchangeable-lens digital 
cameras compatible with EF-M lenses*.
* Only the following cameras are compatible with EF-M lenses (as 
of July 2012): 
EOS M
•
 
"IS" 
 stands for Image Stabilizer.
•
 
"STM" 
 stands for stepping motor.
 Safety Precautions
• Do not look at the sun or a bright light source through the 
lens. Doing so could result in vision loss or blindness.
•
 
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.
•
 
Please 
 also refer to the handling cautions found in your 
camera’s instructions.
Conventions used in this instruction
 Warning to prevent lens or camera malfunction or 
damage.
 Supplementary  notes on using the lens and taking 
pictures.
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.
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 and used 
in accordance with the instructions, may cause harmful interference to 
radio communications.
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:
•
 
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 LensSee your camera’s instructions for details on mounting and 
detaching the lens.
• After  detaching the lens, place the lens with the rear end 
up to prevent the lens surface and contacts from getting 
scratched. (fig.❶)
•
 
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. (fig. ❷) 
To remove it, reverse the order.
2. ZoomingTurn the lens’ zoom ring to adjust the size of the photo field or 
subject. (fig.❸)
•
 
For 
 wide shots, turn the zoom ring toward the wide end.
•
 
For 
 close-ups, turn the zoom ring toward the telephoto end.
• Be sure to finish zooming before focusing. Zooming after 
focusing can affect the focus.
•
 
Blurring 

may temporarily occur if the zoom ring is quickly 
rotated.
•
 
Zooming 

during still image exposure will result in delayed 
focus. This causes any streaks of light that are captured 
during exposure to be blurred.
3. Manual FocusWhen the camera’s focus mode is set to [MF], focus manually by 
turning the focusing ring (fig.❹).
Quickly rotating the focusing ring may result in delayed focus.
• Focus  mode is set using the camera. Please refer to the 
camera’s instructions.
•
 
After 

autofocusing in [AF+MF] mode, focus manually by 
pressing the shutter button halfway and turning the focusing 
ring (full-time manual focusing).
4. Image StabilizerThis lens is equipped with an Image Stabilizer. This function 
corrects camera shake, allowing users to capture sharp images. 
Also, the Image Stabilizer automatically provides optimal image 
stabilization depending on shooting conditions (such as shooting 
still subjects and following shots). Please set the Image Stabilizer 
ON or OFF using the camera settings. See your camera’s 
instructions for details.
• The  Image Stabilizer cannot compensate for a blurred shot 
caused by a subject that moved.
•
 
The 

Image Stabilizer may not be fully effective if you shoot 
from a violently shaking vehicle or other transportation.
•
 
The 

Image Stabilizer consumes more power than normal 
shooting, so fewer shots can be taken if you use the 
function.
• When  shooting a still subject, it compensates for camera 
shake in all directions.
•
 
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.
•
 
When 

you use a tripod, the Image Stabilizer should be 
turned off to save battery power.
•
 
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.
■ Dynamic IS Function (Movie shooting only)The EF-M18-55mm f/3.5-5.6 IS STM is equipped with dynamic IS, 
effective when shooting while walking since it expands the IS range.
• Achieves  effective IS at the wide end.
•  Automatically  activates when the camera is set to Movie 
Shooting.

5. Hood (sold separately)
The EW-54 hood cuts out unwanted light and protects the front of 
the lens from rain, snow, and dust.
To attach the hood, align the hood’s attachment position mark with 
the red dot on the front of the lens, then turn the hood as shown 
by the arrow until the lens’ red dot is aligned with the hood’s stop 
position mark. (fig.❺)
The hood can be reverse-mounted on the lens for storage.
• If 
the hood is not attached properly, vignetting (darkening of 
the perimeter of the picture) may occur.
•
 
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.
6. Filters (sold separately)You can attach filters to the filter mounting thread on the front of 
the lens.
Only one filter may be attached.
