FOR SAFE USE OF YOUR LENS 1
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.

PRECAUTIONS AND LENS MAINTENANCE
2
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 sat-
urated desiccant in the storage container can cause damage to the lens. Be sure to read the
instructions that came 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.

About the DA lens mount
The DA lens is an interchangeable lens
specifically designed for the PENTAX
digital SLR camera.
The KAF -mount of the DA lens is similar to
conventional SLR lenses, but the DA lens
cannot be used on 35 mm SLR cameras.
CAUTION :
•Be careful not to damage or dirty the lens information contacts and AF coupler on the
mount surfaces of the camera and lens. Otherwise, failure or malfunction may result.
If this occurs, wipe them gently with a clean, dry cloth.

ZOOMING 7
The DA 16-45 mm f/4ED AL lens has a two-ring system, where the focusing ring and the
zooming ring are separate. You can set the desired focal length by turning the zoom ring.
✍Memo :
•The focusing point may shift slightly by changing the focal length. First adjust the zoom
and then adjust focus using Autofocus or the focus indicator in the viewfinder.
About the zoom ring
Turn the zoom ring clockwise for telephoto and counterclockwise for wide-angle.
DAE_BodyA 12/2/03 3:44 PM Page 7

FOCUSING
8
Autofocus mode
Set the focus mode lever on the camera to AF.S (single mode) or AF.C (continuous mode),
and press the shutter release button halfway down to start the autofocus operation.
✍Memo :
•During autofocus, do not touch the focusing ring of the DA 16-45 mm f/4ED AL lens, otherwise
you will interfere with proper lens movement and damage the DA lens.
Manual focus mode
Set the focus mode lever on the camera to MF (manual focus mode), then focus by turning
ring and checking the focus indicator in the viewfinder.
✍Memo :
•It is possible to focus manually without changing the focus mode to MF after adjusting the focus
on the subject in the AF.S mode. (☞p9 Quick-shift focus system)
DAE_BodyA 12/2/03 3:44 PM Page 8

Quick-shift focus system
After adjusting the focus on the subject in the AF.S mode, the focusing ring can be turned
to focus manually without changing the focus mode to MF.
✍Memo :
•Do not take your finger off the shutter release button or AF button when focusing
manually in the AF.S mode. If you take your finger off the button and then focus
manually, autofocus will operate to adjust focus again when you press the shutter release
button.
•It is possible to focus manually in AF.S or AF.C mode and release the shutter without
activating the autofocus by setting the "AF with Press Halfway" custom function to "Off."
Press the AF button to use autofocus when "AF with Press Halfway" is set to "Off."

Precautions on close-distance scale
In the close-distance scale range (the distance scale in the orange area), and when shoot-
ing 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, stop-
ping down from wide open.

LENS HOOD 11
Lens hood
In order to avoid the deterioration in image quality from internal reflection, use of the lens
hood is recommended.
LENS HOOD for DA16-45mm f/4ED AL
How to attach
To attach the lens hood to the lens, align ( l ) on the lens hood to ( l ) on the lens, and push
both parts straight towards each other. Turn the lens hood clockwise to lock it into place.
✍Memo :
•When attaching the lens hood, hold the focus ring and zoom ring securely to prevent
them from turning.

FILTERS
14
The filter is mounted into the screw thread in front of the lens.
Precaution on filters
•Attaching the filter to your lens becomes a part of the optic. Avoid using more than one fil-
ter at a time, with the exception of a polarizing filter, as deterioration in image quality may
results.
•Use a circular polarizing filter with Autofocus camera for proper exposure and
autofocusing.
Precautions for using the exclusive lens hood
•When using the PENTAX circular polarizing filter, which has a knurl ring on the back, with
the DA16-45 mm f/4ED AL lens, the exclusive lens hood cannot be attached.
•The exclusive lens hood also may not be possible to attach with some non-PENTAX
circular polarizing filters.

PRECAUTIONS WHEN USING THE LENS WITH A FLASH 15
Built-in FLASH
●Minimum distance from flash to subject with the built-in flash
The built-in flash can not be used when the distance is less than 0.7 m. When the flash is
used within 0.7 m, it causes incorrect exposure control and vignetting in the picture corners.
●Focal length
The light is not distributed evenly and vignetting occur at focal lengths between 16mm to
28mm, and the focal length at 28 mm and focus distance less than 1m.
External FLASH
When using the external flash, vignetting will not occur with the lens hood.
For further details, refer to the operating manual for your external flash.
