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.

20  
CAUTION  
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.

(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.

Built-in lens hood  
The following lenses have a lens hood built into the lens body. The hood cannot be  
removed from the lens.  
• DA FISH-EYE 10-17mm f/3.5-4.5ED [IF]  
• DA 35mm f/2.8 Macro Limited (*), DA 15mm f/4ED AL Limited (*)  
Lenses marked with an * have a built-in sliding hood which should be extended.  
 
32  
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.  
 
33  
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 filter.  
 
34  
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.  
 
35  
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 PENTAX circular polarizing filters (currently not in  
production) 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.

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.  
zDA 14mm f/2.8ED [IF]  
zDA 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.  
zDA 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.  
zDA 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.  
 
41  
zDA 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.  

zDA 16-50mm f/2.8ED AL [IF] SDM  
zDA 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.
