This smc PENTAX-DA lens features a “Quick-Shift Focus System” that lets you finely
adjust the focus manually after the focus has been adjusted in addition to allowing
you to enjoy taking pictures using autofocus or manual focus by mounting on the
PENTAX-series digital SLR camera. For further information on the use of this
function, refer to p11.
smc PENTAX-DA lens can be used only with PENTAX-series SLR
cameras. It is not compatible with film SLR cameras.
Please read this operating manual carefully before using the lens to ensure that it is
used properly. In addition, also refer to your camera’s operating manual.
In this operating manual, “smc PENTAX-DA lens” is shortened to “DA lens.”
Illustrations shown herein may differ from the actual appearance.
FOR SAFE USE OF YOUR LENS
Although we have carefully designed these lenses for safe operation, please pay special
attention to items marked with the following symbols when using this product.
1
WARNINGThis symbol indicates precautions that if not followed,
could result in serious injury to the user.
CAUTIONThis symbol indicates precautions that if not followed,
could result in minor or medium injury to the user or
damage to the equipment.
WARNING
• Never look at the sun through the lens or camera. Serious damage to the retina or
total loss of eyesight may occur.
CAUTION
• Do not leave the lens in direct sunlight without lens caps. Direct sunlight passing
through the lens will be intensified, and should it focus on flammable materials, fire
may occur.

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 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.

Precautions on close-distance scale
(For DA 16-45mm f/4ED AL, DA18-55mm f/3.5-5.6 AL)
In the close-distance scale range (the distance scale in the orange area), when shooting at
the maximum aperture, image quality deterioration in the picture corners may result
because of the optical characteristics of the lens.
When taking a picture in this range, we recommend that you use a smaller aperture,
stopping down from wide open.

The zoom lens has a focusing ring at the front and a zoom ring behind it.
Turn the zoom ring to set the desired angle of view (lens focal length).
Memo:
✍
• The focusing point may shift slightly by changing the focal length. First adjust the zoom
and then adjust focus.
About the zoom ring
Turn the zoom ring clockwise for telephoto and counterclockwise for wide-angle.

In order to avoid the deterioration in image quality from internal reflection, use of the lens
hood is recommended.
ATTACHING THE LENS HOOD
12
1. Screw-on Type
If the lens hood is dedicated to the DA 40mm f/2.8 Limited, screw it onto the front of the
lens.
2. Bayonet Type
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.
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.

About the PL filter window
If a circular polarizing filter is attached to the DA lens, you can easily turn the filter via the
PL filter window on the bayonet-type hood.

- DA 18-55mm f/3.5-5.6 AL- DA 50-200mm f/4-5.6ED
How to use the lens hood with polarizing filter window
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.
Memo:
✍
• When shooting, be sure the PL filter window cap is in place to make that the lens hood
is being used to maximum effect.
FILTERS
Make sure the filter size matches the lens, then screw the filter onto the front of the lens.
Memo:
✍
• The compatible filter size for all the lenses are listed on pages 24-26.
• Filters cannot be mounted on the DA FISH-EYE 10-17 mm f/3.5-4.5ED (IF).
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.
Attaching the 30.5mm filter to the DA 40mm f/2.8 Limited lens
Normally, you attach the 49mm filter to the front of the lens. But as shown in the diagram,
you can also screw on a 30.5mm filter to the back of the dedicated hood.

Notes
PRECAUTIONS WHEN USING THE LENS WITH A FLASH
Built-in Flash
The built-in flash can not be used when the distance is less than 0.7m. When the flash is
used within 0.7m, it causes incorrect exposure control and vignetting in the picture corners.
• Refer to the “Compatibility of DA Lenses with the Built-in Flash” chart on page 23 for
information on the compatibility of the built-in flash with the lens being used. Furthermore,
please note that when using the-series camera, a warning indication does not
appear even when taking a picture with a built-in flash that is incompatible with the lens
being used.
• If the built-in flash is used with the lens hood attached to the lens, the flash light will be
blocked by the lens hood. Always make sure to remove the lens hood before using the
built-in flash.
External Flash
The external flash can be used while the lens hood is attached. However, the following
conditions apply for some types of lens.
● DA 14mm f/2.8ED (IF)
The AF540FGZ and AF360FGZ external flash units can only be used when the wide-angle
panel is used (it is also possible to use the lens hood). Other external flash units are not
recommended because their coverage angle is not compatible with the angel of view of the lens.
● DA FISH-EYE 10-17 mm f/3.5-4.5ED (IF)
External flash units cannot be used because their coverage angle is not compatible.
21
22
● DA 12-24 mm f/4ED AL (IF)
Pentax external flash units which support TTL auto flash and that cover a 24mm lens on a
35mm SLR or 16mm lens on a digital SLR can be used from 16mm to 24mm.
AF540FGZ and AF360FGZ can be used from 13mm to 24mm with the wide angle panel (In
both cases, it is possible to use the lens hood).
Please note that at focal lengths less than 13mm the corners of the picture will not be fully
illuminated.
Other external flash units are not recommended because their coverage angle is not wide
enough to cover the angle of view of the lens.
● DA 16-45 mm f/4ED AL
PENTAX external flash units which support TTL auto flash and that cover a 24mm lens on a
35mm SLR or 16mm lens on a digital SLR can be used (it is also possible to use the lens hood).
*For more information, refer to the manual for the external flash unit. Please check your
camera instruction manual for information on which flashes can be used with your PENTAX
Digital SLR.
