1. Storage and mildew prevention
•
Take the lens out of the protective case or camera bag, and store it in a dry, well-ventilated 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 in a dry cabinet, airtight container, or plastic bag.
(Leaving a saturated desiccant in the storage container can cause damage to the lens. Be sure
to read the instructions that come with the desiccant before use.)
2.
The lens is not waterproof. When using the lens in a rain or mist, be careful not to allow it to get wet.
3. Never use any organic solvent such as thinner, alcohol, or benzine, etc. to remove dust on the lens.
4. 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.
5. Avoid subjecting the lens to rapid changes in temperature, otherwise condensation can occur on
both the inside and the 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.
6. When the lens is not attached to the camera body, attach both the supplied lens cap and lens
mountcap to protect it from dust.
7. 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.
8. Have the lens inspected by a dealer every one or two years to maintain its high performance.

Lens hood
attaching
index
In order to avoid the deterioration in image quality from internal reflection, use of the lens
hood is recommended.
ATTACHING THE LENS HOOD
When attaching the lens hood, align the index on the lens hood with the attaching index on
the lens, and push both parts straight toward each other. Attach the lens hood on the lens
by turning the hood in the clockwise direction to lock it as viewed from the front of the lens
until it clicks into position.
2. Memo:
•When attaching the lens hood, hold the focus ring and zoom ring securely to prevent
them from turning.
•When the lens hood is not in use, it can also be turned around and attached in the
reversed position.
The lens hood image can be diifferent
depending on the lens hood type.

《15》
Make sure the filter size matches the lens and then attach the filter onto the lens.
FILTERS
2. Precaution on filters
•Since the filter becomes a part of the optics when attached on the lens, handle it in
the same way you handle the lens with care to dust, dirt and scratches.
Normally, attaching two or more filters on a lens is not recommended.
However, attaching a circular polarizing filter and another filter would not be a
problem.
•Use a circular polarizing filter with Autofocus camera for proper exposure and
autofocusing.

《16》
PRECAUTIONS WHEN USING THE LENS WITH A FLASH
Built-in Flash
When the flash is used for too close distance, the incorrect exposure control and
vignetting in the picture may occur. It is recommended to take a test shot before using
the built-in flash.
•The built-in flash may be blocked by the lens hood. Always make sure to remove the
lens hood before using the built-in flash.
