Introduction
Responding to Malfunction or Accidents
 Warning
1.  If any of the following situations occurs, immediately disconnect the lens cable from the camera 
and contact your dealer or a Canon representative listed on the next page. 
 
• Smoke, fumes, or unusual noises coming from the lens 
 
• Foreign objects (such as liquid or metal objects) inside the lens 
Maintenance and Inspection
 Warning
1.  Before cleaning the lens, always disconnect the lens cable and remove the lens from the camera. 
Do not use benzene, thinner, or other fl ammable substances to clean the lens. This may cause 
fi re or electric shock.
Note
1.  Clean off any dust on the lens using a lens blower or a soft lens brush. 
 
In case of fi ngerprints or stains on the lens, use a clean cotton cloth moistened with commercial 
lens cleaning fl uid, or use lens cleaning paper. Gently wipe in a spiral pattern from the center of 
the lens.
 
Be careful not to rub dust across the lens, which may scratch the lens surface. 
2.  Routine inspection about once a year is recommended, depending on the conditions and 
environment of use. Request overhaul, if needed.
Storage
 Caution
1.  Always attach the lens cap (or hood cap) and dust cap before storage. Storing the lens without 
the caps attached poses a risk of fi re if the lens focuses a light source.
Note
1.  Immediately wipe off any moisture on the lens from misty or foggy environments, using a dry 
cloth. Seal the lens in a plastic bag with a desiccant (preferably new) to prevent moisture inside.
