• 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.

FILTERS
"Memo:
• The compatible filter size for each lens is listed on pages 46-51.
• 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.
3333
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.

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

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 lens.
zDA 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.
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.
4141
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.
