Precautions When Using the Lens

 Storage and mildew prevention

• Take the lens out of the protective case or camera bag,
and store it in a dry, wellventilated place.

• Avoid storing the lens in a poorly ventilated location such as a closet,
wardrobe, drawer, vehicle, or where insect repellent or medicine
is kept.

• Avoid storing the lens in areas of high temperature and humidity,
where there is a risk of mildew growth. Store the lens with a
desiccant (anti- mildew agent) in a dry cabinet, airtight container,
or plastic bag.

 Precautions and lens maintenance

• Never use any organic solvent such as thinner, alcohol, or benzine,
etc. to remove dust on the lens.

• The lens is a precise optical instrument. Be careful not to let it fall,
or subject it to strong shocks or pressure. Use a cushion or similar
pad to protect the lens from the vibrations of motorcycles or other
vehicles, boats, etc.

• Avoid subjecting the lens to rapid changes in temperature, otherwise
condensation can occur on both inside and outside of the lens.
Put the lens in a plastic bag or camera bag, and take it out after
the lens has reached ambient temperature.

• When the lens is not attached to the camera body, attach both
the supplied lens cap and lens mount cap to protect it from dust.

• Do not leave the camera with the lens cap off attached to a tripod
or other rigid camera support. The inner parts of the camera can
be damaged by direct sunlight.

* Have the lens inspected by a dealer every one or two years to maintain

its high performance.

manually after autofocus is performed, by using the “Quick-Shift
Focus System”.

• This lens is made with a simplified weather-resistant construction
which makes it difficult for water to enter the lens.
