Precautions When Using the Lens
Storage and mildew prevention
• Take the lens out of the protective case or camera bag, and store it in a dry, wellventilated place.
• Avoid storing the lens in a poorly ventilated place 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 (anti-mildew agent) in a dry
cabinet, airtight container, or plastic bag.
Precautions and lens maintenance
• Never use any organic solvent such as thinner, alcohol, or benzine, etc. to remove
dust on the lens.
• 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, automobiles, boats, etc.
• Avoid subjecting the lens to rapid changes in temperature, otherwise condensation
can occur both inside and 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.
• Wipe the lens to dry off any rain or water drops immediately.
• Do not attach or remove the lens when there are any rain or water drops on the
camera. If water enters the camera or the lens, a malfunction may occur.
• 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.

• 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.
* Have the lens inspected by a dealer every one or two years to maintain its high performance.
Features of This Lens
• This lens uses our proprietary multi coating: "HD (High Definition) Coating", which
has higher transmission of light with less reflection than existing coatings. This
coating prevents flare and realizes to achieve image quality with excellent contrast.
• Equipped with "Quick-shift Focus System" (can be switched with the focus mode
switch), you can focus manually even while autofocus is operating, not just after
autofocusing.
• This lens has a dust-proof and water-resistant construction with each part
individually sealed.
• SP (Super Protect) Coating applied to the front surface of the lens to effectively
repel water and grease and easily wipe off dust and stain.
• Equipped with the preset button and AF button to allow expansion of autofocus
functions (*) by switching modes.
"AF Button and Preset Button" (reverse side)
(*) Available when using with cameras that support expanded autofocus functions.
For details of the compatible cameras, refer to our website below.

When shooting against backlight, keep the sun sufficiently out of the angle of
view. Direct sunlight may focus as an image on the inner parts of the camera,
and then burn or damage them, or cause a fire.
Do not leave the lens in direct sunlight without a lens cover or lens cap. Direct
sunlight passing through the lens will be intensified, and should it focus on
flammable materials, fire may occur.

About the Lens Mount
This "KAF3 mount" enables autoexposure, and
autofocus operated by a DC motor in the lens.
When using a camera that is not compatible with
the internal motor, autofocus is not available.

KAF3 mount
CAUTION
Be careful not to damage or dirty the lens information
contacts and the power supply contacts on the mount
surface of the lens. Otherwise, failure or malfunction
may result.
* This lens does not have an aperture ring. Aperture settings are controlled
automatically as if set to the auto “A” position, so accessories without an auto “A”
setting cannot be used with this lens.
About the Lens Hood
Using a lens hood is recommended to block stray light from entering the lens.
The internal reflection of stray light degrades image quality.
<How to attach>
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, as viewed from the front of the lens, to lock it
until it clicks into position.
* When the lens hood is not in use, it can also be turned around and attached in
the reversed position.
The included lens hood has a PL filter window which
facilitates the manipulation of the circular polarizing filter
when the lens hood is attached.
<How to use>
1. Remove the PL filter window cap by sliding it in the
direction as shown in the illustration.
2. Turn the outer rim of the circular polarizing filter from
the PL filter window as shown in the illustration.
3. Attach the PL filter window cap.
* When shooting, be sure the PL filter window cap is in
place to achieve maximum effect of the lens hood.

About Lens Filters (commercially available)
Screw a commercially available 86 mm diameter filter to the front of the lens.
CAUTION
• Since a filter becomes a part of the optical system when attached to the lens, handle
it with due care to protect it from dust, dirt and scratches.
• Use a circular polarizing filter if you attach a filter to a PENTAX digital SLR camera.
If you use a normal polarizing filter, exposure and autofocus are less-accurate.
About the Zoom Lock Switch
This lens is equipped with a zoom ring lock. This prevents
the lens from extending under its own weight while you
are carrying the camera.
Set the zoom ring to the shortest focus (150 mm), and
move the lock switch in the direction of the arrow. The
lock is engaged and the zoom ring is immovable when
the red line is visible.

Focusing
Focus Mode Switching
Use the focus mode switch to switch between autofocus
and manual focus.
Place the switch at QFS/A or QFS/M to use autofocus.
Place the switch at MF to use manual focus.
* Set the camera's focus mode to autofocus (AF).
CAUTION
Keep pressing the shutter release button (or AF button) after you achieve proper focus
and before taking a picture. If you let go of the shutter release button before taking a
picture, autofocus will operate again when you press the shutter release button again.
Focus Range Limiter
Using the Quick-shift Focus System
On cameras that support this function, you can adjust the focus position by holding
down the shutter release button halfway (or holding down the AF button) in
autofocus mode and then turning the focusing ring.
QFS/A : After focusing with the autofocus, you can adjust the focus manually.
QFS/M : You can adjust the focus manually while the autofocus is operating.
AF Button and Preset Button
Available only when using with cameras that support expanded autofocus
functions.
You can assign the following operation modes to the AF button (1)
by changing the mode selector switch (3) position.
1
AF
: Activates autofocus.
PRESET MODE: Returns to a focus position previously recorded on
the lens' memory. (Focus Preset Mode)
2
AF CANCEL
: Temporarily cancels autofocus operation on the
camera's side. Also fixes the focus position by
pressing the AF button after focusing.
About Focus Preset Mode
1. To record a focus position, after focusing, hold down the
3
PRESET button (2). You will hear a beep when it is recorded.
2. Press the AF button to return to the recorded focus position
(AF stops at the point where you release the button while
returning).
CAUTION
The focus position may shift when you turn the camera off or change the focal length
by zooming.
You can use the autofocus more effectively by switching the
focus range limiter to limit the operating range of the autofocus
to close range (2 to 6 m) or to far range (6 m to ∞).
* When it is at "FULL", the limiter is canceled, and the
autofocus range is from 2 m to ∞.
* The limiter does not operate in manual focus.
Tripod Mount
This lens is equipped with a tripod mount (removable), and can be set on a tripod.
Switching Between Horizontal and Vertical Shooting
Loosen the camera orientation lock screw and turn the camera by 90° left or right.
Then tighten the camera orientation lock screw.
Removing the Tripod Mount
1. Loosen the mounting screw.
2. While pressing on the mounting screw (1), slide
the tripod mount in the direction of the arrow (2),
as shown in the diagram to the right.

mounting screw otherwise the camera may shake or the lens may fall off. We also
recommend using a fast shutter speed.
