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.

• This lens does not have an aperture ring. Aperture setting is controlled automatically
as if set to the auto "A" position, so exposure modes and accessories which don't
support an auto "A" position cannot be used with this lens.

About
the
Lens
Hood
Using a lens hood is recommended to block stray light from entering the lens.
The internal reflection of stray light degrades image quality.
<How to attach>
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, as viewed from the front of the lens, to lock it
until it clicks into position.
• When the lens hood is not
in
use, it can also be turned around and attached
in
the reversed position.
A
PL
filter window is attached
to
the hood included with this
lens
to
make manipulating the circular polarizing filter easier.
<How to use>
1.
Remove the PL filter window cap by sliding it
in
the
direction as shown above.
2.
Turn the outer rim of the circular polarizing filter from
the PL filter window as shown above.
3.
Attach the PL filter window cap.
• When shooting, be sure the PL filter window cap is
in
place to use the lens hood to maximum effect.
