Thank you for purchasing a Canon product.
The Canon EF-M 18-55mm 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 September 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.
1. Mounting and Detaching the Lens
See 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. Zooming
Turn 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 Focus
When 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 Stabilizer
This 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-M 18-55mm 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.
