Thank you for purchasing a Canon product.
The Canon EF-M55-200mm f/4.5-6.3 IS STM lens is a
telephoto zoom lens developed for digital cameras compatible
with EF-M lenses*.
* Only the following cameras are compatible with EF-M lenses (as
of February 2014):
EOS M, EOS M2*
: Not available in certain countries and regions.
"IS" stands for Image Stabilizer.
"STM" stands for stepping motor.
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.
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

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
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.
Turn the lens’ zoom ring to adjust the size of the photo field or
For wider shots, turn the zoom ring toward the wide end.
For closer shots, 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
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
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, resulting in fewer shots and a shorter movie
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
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.
