PRECAUTIONS 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. Be careful when handling lenses that are not dust-proof, water-resistant, or do not have simplified weather-resistant construction in the rain, fog or environments in which sand or dust is in the air. 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.

FEATURES 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 image sensors in PENTAX digital SLR cameras 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 19 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 DA 55mm f/1.4 SDM uses a circular aperture. Using it when stopping down from full aperture to about f/2.8 keeps light sources and other fuzzy points perfectly round.

About dustproof, water resistance, and simplified weather resistance
Dust-proof and water-resistant lenses DA 55mm f/1.4 SDM, 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, DA 60-250mm f/4ED [IF]SDM These DA lenses are dust-proof and water-resistant because each part is individually sealed. This makes it difficult for dust and water to enter the lens. Lenses with simplified weather-resistant construction DA 18-55mm f/3.5-5.6 AL WR, DA 50-200mm f/4-5.6ED WR These lenses are made with a simplified weather-resistant construction by using DA lens sealing technology which makes it difficult for water to enter the lens.

e_da21_20.fm Page 20 Thursday, April 23, 2009 5:34 PM
When using the Quick-Shift Focus System, keep pressing the shutter release button (or AF button) after you achieve focus and before taking a picture. If you let go of the shutter release button before taking the picture, autofocus will operate again when you press the shutter release button again. However, by configuring the camera's custom settings, you can take pictures without autofocusing after letting go of the shutter release button. See the camera operating manual for details about the setting procedure. When focusing with manual focus or the Quick-Shift Focus System, the mechanism allows the focusing ring to rotate freely after it is set to the (infinity) or the minimum focus distance ends. However do not attempt to rotate it any farther than these ends as this will result in decreased performance. - DA 14mm f/2.8ED [IF] - DA 55mm f/1.4 SDM - DA 200mm f/2.8ED [IF] SDM - DA 300mm f/4ED [IF] SDM - DA 16-50mm f/2.8ED AL [IF] SDM - DA 50-135mm f/2.8ED [IF] SDM - DA 60-250mm f/4ED [IF] SDM

DA 200mm f/2.8ED [IF] SDM, DA 300mm f/4ED [IF] SDM focusing
The mechanism does not allow the angle of rotation of the focusing ring and the distance scale to align while focusing. Always check the focus using the view finder before taking a picture. This is especially true with manual focus and the Quick-Shift Focus System.
e_da21_20.fm Page 22 Thursday, April 23, 2009 5:34 PM
Precautions on close-distance scale (For DA 16-45mm f/4ED AL, DA 18-55mm f/3.5-5.6 AL WR, DA L 18-55mm f/3.5-5.6 AL)
In the close-distance scale range (minimum focus distance range), when shooting at the maximum aperture, image quality in the corners of the picture may deteriorate 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 full aperture.

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 each lens is listed on pages 47-53. Filters cannot be mounted on the DA FISH-EYE 10-17mm f/3.5-4.5ED [IF].

Precaution on filters

Since a filter becomes a part of the optical system when attached to 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 does more harm than good. However, attaching a circular polarizing filter and another filter is not a problem. Use a circular polarizing filter with an 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 you can also screw a 30.5mm filter to the back of the dedicated hood.

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 42 for information on the compatibility of the built-in flash with the lens being used.

External Flash

The external flash can be used while the lens hood is attached. However, the following conditions apply to some types of lenses.
DA 14mm f/2.8ED [IF] DA 15mm f/4ED AL Limited
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 angle of view of the lens.

PRECAUTIONS 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.

FEATURES 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 17 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 [IF] SDM, DA 50-135mm f/2.8ED [IF] SDM

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 each lens is listed on pages 44-49. Filters cannot be mounted on the DA FISH-EYE 10-17mm f/3.5-4.5ED [IF].

Precaution on filters

Since a filter becomes a part of the optical system 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 does more harm than good. However, attaching a circular polarizing filter and another filter would not be a problem. Use a circular polarizing filter with an 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 you can also screw a 30.5mm filter to the back of the dedicated hood.

Attaching a filter and the dedicated lens hood to the DA 21mm f/3.2 AL Limited lens
It is possible to attach a 49mm diameter filter to the front of the DA 21mm f/3.2 AL Limited lens, but not when the dedicated lens hood is attached. To use a filter with the dedicated lens hood, screw a 43mm diameter filter to the back of the lens hood.

Attaching a filter and the dedicated lens hood to the DA 70mm f/2.4 Limited lens
With the DA 70mm f/2.4 Limited lens, attach the 49mm diameter filter to the front of the lens. To use it together with the dedicated lens hood, screw it on over the filter that is attached. Memo: The lens hood cannot be mounted on some circular polarizing filters that are not produced by PENTAX, depending on the type.

Circular polarizing filters and vignetting
Circular polarizing filters are thicker than regular filters. Depending on the lens that is mounted and the shooting conditions, vignetting may occur in the four corners of the image. Refer to the Compatibility table for PENTAX circular polarizing filters on the following page for information on compatibility of the PENTAX circular polarizing filters (currently not available) with various lenses. There are two types of PENTAX circular polarizing filters: the A type (on the left in the diagram below) and the B type (on the right in the diagram below). The B type filter is thinner than the A type filter.

Compatibility table for PENTAX circular polarizing filters
* PENTAX circular polarizing filters are not currently available. * PENTAX does not produce a circular polarizing filter with a 62mm diameter that can be used with the DA 18-250mm f/3.5-6.3ED AL [IF]. YES: Compatible *YES: Compatible in some conditions NO: Incompatible

External Flash

The external flash can be used while the lens hood is attached. However, the following conditions apply to 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 angle of view of the lens.

DA 21mm f/3.2 AL Limited

External flash units can be used while the lens hood is mounted without problems if it is possible to set their zoom [coverage angle] up to 28mm.
DA FISH-EYE 10-17mm f/3.5-4.5ED [IF]
External flash units cannot be used because their coverage angle is not compatible with the angle of view of the lens.
e_kl567_16.fm Page 39 Wednesday, April 23, 2008 11:42 AM

DA 12-24mm f/4ED AL [IF]

PENTAX external flash units which cover a 24mm lens on a 35mm SLR, or 16mm lens on a digital SLR, can be used when the lens is set 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 16-50mm f/2.8ED AL [IF] SDM DA 16-45mm f/4ED AL
PENTAX external flash units which cover a 24mm lens on a 35mm SLR, or 16mm lens on a digital SLR, can be used with the lens hood without problems. * For more information, refer to the manual for the external flash unit.
