HANDLING THE

WARNING

high-intensity light through the lens. Doing
so could injure your eyes.
CAUTION
1. Make sure all mountings are tightened
securely. If any of these mountings
becomes loose, the lens may fall, possibly
causing injury.
2. Inspect all mountings periodically (about
every 6 months to 1 year) to make sure
they are securely tightened, and tighten
any loose parts. Otherwise, the lens may
fall, possibly causing injury.
3. If it becomes necessary to repair this
product, or to perform any operations or
adjustments not mentioned in this operation
manual, contact Canon’s representative or
the dealer who originally supplied the lens.
NOTE
1. Protect the lens from strong impacts or
shocks. Striking or dropping the lens may
result in a malfunction.
2. This lens is not completely waterproof,
so avoid exposing it directly to rain or
snow. When the lens must be used in rain
or snow, provisions should be made to
prevent the lens from getting wet.
3. Do not bring the lens, kept in a very cold
ambient temperature, into a warm room,
because the lens may fog on the inside or
condensation may occur.
In these cases, the lens cannot be used
until these problems clear.
If the lens must be used under such
conditions, countermeasures are
recommended.
