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, well-
ventilated place.
• Avoid storing the lens in a poorly ventilated place 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, automobiles, boats, etc.
• Avoid subjecting the lens to rapid changes in temperature, otherwise condensation
can occur 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 settings are controlled
automatically as if set to the auto "A" position, so accessories without an auto "A"
setting 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.
The included lens hood has a PL filter window which
facilitates the manipulation of the circular polarizing filter
when the lens hood is attached.
<How to use>
1. Remove the PL filter window cap by sliding it in the
direction as shown in the illustration.
2. Turn the outer rim of the circular polarizing filter from
the PL filter window as shown in the illustration.
3. Attach the PL filter window cap.
* When shooting, be sure the PL filter window cap is in place to achieve
maximum effect of the lens hood.

Features of This Lens
• This lens uses our proprietary multi coating: "HD Coating (High Definition Coating)",
which has higher transmission of light with less reflection than existing coatings.
This coating prevents flare and realizes to achieve image quality with excellent
contrast.
• You can focus manually without switching the focus mode after autofocus is
performed by using the "Quick-shift Focus System".
• This lens has a water-resistant construction with each part individually sealed.
• SP (Super Protect) coating applied to the front surface of the lens to effectively
repel water and grease and easily wipe off dust and stain.

may result.
About Lens Filters (commercially available)

Screw a commercially available 72 mm diameter filter to the front of the lens.
CAUTION
• Since a filter becomes a part of the optical system when attached to the lens, handle
it with due care to protect it from dust, dirt and scratches.
• Use a circular polarizing filter if you attach a filter to a PENTAX digital SLR camera.
If you use a normal polarizing filter, exposure and autofocus are less-accurate.
