The Canon EF-M 22mm f/2 STM lens is a small fixed
focus length 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):

• 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.
