Canon CN-E15.5-47mm T2.8 L S Operation Manual page 18

MAINTENANCE AND
INSPECTION
NOTE
1. Gently blow or brush away dust or dirt on
the lens surface using a lens blower or a
soft lens brush. Remove any fingerprints or
other stains with a soft clean cotton cloth
moistened with commercially available lens
cleaning fluid or lens cleaning paper.
Be careful not to rub dust across the lens,
as the lens surface may be scratched.
2. A periodic inspection about once a year is
recommended.
The inspection and maintenance interval
depends on the operating conditions, the
frequency of use, and the environment. If
required, overhaul the lens.
STORAGE
CAUTION
1. Always attach the lens cap (or hood
cap) and the dust cap before storing the
lens. Storing the lens without these caps
attached may present a fire hazard. (Very
bright light, such as sunlight, may be
focused by the lens and cause a fire.)
