WARNING
•Never look at the sun through the lens
or camera. Serious damage to the reti-
na, or total loss of eyesight may occur.
•Wrapping the strap around your neck is
dangerous. Make sure that small chil-
dren do not get the strap caught their
neck. (A strap is supply only with some
large types of lenses)
CAUTION
•Do not leave the lens in direct sunlight
without lens caps. Sunrays passing
through the lens will be intensified, and
should they focus on flammable materi-
als, fire may occur.
FOR SAFE USE OF YOUR LENS

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 satu-
rated desiccant in the storage container can cause damage to the lens. Be sure to read the
instructions that came 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
mount cap 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.

The Pentax FA lenses are primarily designed
to work with the Pentax autofocus SLR (KAF-
or KAF2-mount camera), making autofocus
shooting possible.
When Pentax FA Zoom lenses with power
zoom function are used on the Pentax KAF2-
mount camera, the camera features a Power
Zoom system.
•An FA zoom lens without the power zoom
contacts are shown in the illustration does
not have the power zoom function.
•Do not damage or dirty the power contacts.

•When using FA lens with the K-mount
Pentax camera having no lens information
contacts, be sure to set the lens aperture
ring to any f-stop other then A. If set to the
"A" position, the lens will automatically be
set to the minimum aperture, causing
improper exposure.
CAUTION :
•Be careful not to damage or dirty the lens
information contacts and AF coupler on the
mount surfaces of the camera and lens.
Otherwise, failure or malfunction may
result. If this occurs, wipe them gently with
a clean, dry cloth.
•FA J18-35mm f/4-5.6AL, FA J28-80mm
f/3.5-5.6AL and FA J75-300 mm f/4.5-
5.8AL lenses have no aperture ring to set a
f-stop manually. Aperture settings are con-
trolled automatically as if set to the auto "A"
position, so accessories without an auto
"A" setting cannot be used with these lens-
es.

There is a white dot next to the maximum f-
number engraved on the lens's aperture ring
on many Pentax lenses. This white dot indi-
cates an aperture which is darker by one stop
(larger number). The illustration below shows
the white dot next to f/4.5 is f/5.6.
The click stops between two engraved f/stops
are equivalent to intermediate f-stops. Some
lenses do not have an intermediate click f-
stop on the aperture ring due to limited space
between the f-numbers engraved on the
aperture ring.
