attention to items marked with the following symbols when using this product.
WARNING This symbol indicates precautions that if not followed,
could result in serious injuries to the user.
CAUTION This symbol indicates precautions that if not followed,
could result in minor or medium injuries to the user or
damage to the equipment.
WARNING
• Never look at the sun through the lens or camera for a long time. Serious damage
to the retina or total loss of eyesight may occur, particularly when looking directly

2PRECAUTIONS AND LENS MAINTENANCE
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 following lenses are dust and water resistant.
(DA300mm f/4ED [IF] SDM, DA200mm f/2.8ED [IF] SDM, DA16-50mm f/2.8ED AL [IF] SDM,
DA50-135mm f/2.8ED [IF] SDM)
Lenses other than those listed above are not dust and water resistant. Be careful not to allow dust,
dirt, water, harmful gases, salt, or other materials to get on those lenses.
3. 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, etc.
4. Never use any organic solvent such as thinner, alcohol, or benzine, etc. to remove dust on the lens.
5. 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.
6. 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.
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.

6FEATURES OF THE smc PENTAX-DA LENS
• The smc PENTAX-DA lens is an interchangeable lens specifically designed for digital
cameras. Its image circle is specialized for the image sensor (23.5 x 15.7mm) and its
optical system is optimized for the characteristics of digital images.
• When autofocusing is finished, it is possible to make fine adjustments by hand using the
“Quick-Shift Focus System” (see page 18 for details).
• Lenses that have “SDM” in their name are equipped with a supersonic motor. When
mounted on a camera that supports supersonic motors, the autofocus is quiet and
smooth.
• The following lenses are dust and water resistant because each part is individually
sealed. This makes it difficult for dust and water to enter inside the lens.
DA300mm f/4ED [IF] SDM, DA200mm f/2.8ED [IF] SDM, DA16-50mm f/2.8ED AL
