    Thank you for purchasing a Canon product.The Canon EF-M22mm 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 July 2012): 
    EOS M
     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.
     hether 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.
     not leave the lens in excessive heat such as 
    in a car in direct sunlight.  High temperatures 
    can cause the lens to malfunction.
     also refer to the handling cautions found 
    in your camera’s instructions.
