For the customers in the U.S.A.

THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES.

OPERATION IS SUBJECT TO THE FOLLOWING TWO CONDITIONS:

(1) THIS DEVICE MAY NOT CAUSE HARMFUL INTERFERENCE, AND

(2) THIS DEVICE MUST ACCEPT ANY INTERFERENCE RECEIVED,

INCLUDING INTERFERENCE THAT MAY CAUSE UNDESIRED

OPERATION.

CAUTION

You are cautioned that any changes or modiﬁ cations not expressly approved

in this manual could void your authority to operate this equipment.

NOTE:

This equipment has been tested and found to comply with the limits for a

Class B digital device, pursuant to Part 15 of the FCC Rules. These limits

are designed to provide reasonable protection against harmful interference

in a residential installation. This equipment generates, uses, and can radiate

radio frequency energy and, if not installed and used in accordance with the

instructions, may cause harmful interference to radio communications.

However, there is no guarantee that interference will not occur in a particular

installation. If this equipment does cause harmful interference to radio or

television reception, which can be determined by turning the equipment off

and on, the user is encouraged to try to correct the interference by one or

more of the following measures:

– Reorient or relocate the receiving antenna.

– Increase the separation between the equipment and receiver.

– Connect the equipment into an outlet on a circuit different from that to which the

receiver is connected.

– Consult the dealer or an experienced radio/TV technician for help.

For the customers in Canada

This Class B digital apparatus complies with Canadian ICES-003.

Notes on use

• Do not leave the lens in direct sunlight. If sunlight is focused onto a nearby

object, it may cause a ﬁ re. If circumstances necessitate leaving the lens in direct

sunlight, be sure to attach the lens cap.

• Be careful not to subject the lens to mechanical shock while attaching it.

• Always place the lens caps on the lens when storing.

• Do not keep the lens in a very humid place for a long period of time to prevent

mold.

• After attaching the lens, do not carry the camera by holding the lens.

• Do not touch the lens contacts. If dirt, etc., gets on the lens contacts, it may

interfere or prevent the sending and receiving of signals between the lens and the

camera, resulting in operational malfunction.

Precaution for ﬂ ash use

With certain of lens/ﬂ ash combinations, the lens may partially block the light

of the ﬂ ash, resulting in a shadow at the bottom of the picture. When using a

built-in camera ﬂ ash, make sure to remove the lens hood and shoot from at

least 1m (3.3 feet) away from your subject.

Vignetting

When you use lens, the corners of the screen become darker than the center.

To reduce this phenomena (called vignetting), close the aperture by 1 to 2

stops.

Condensation

If your lens is brought directly from a cold place to a warm place,

condensation may appear on the lens. To avoid this, place the lens in a plastic

bag or something similar. When the air temperature inside the bag reaches

the surrounding temperature, take the lens out.

Cleaning the lens

• Do not touch the surface of the lens directly.

• If the lens gets dirty, brush off dust with a lens blower and wipe with a soft,

clean cloth (Cleaning Cloth KK-CA (optional) is recommended).

• Do not use any organic solvent, such as thinner or benzine, to clean the lens or

the camera cone.

Attaching/detaching the lens

To attach the lens (See illustration



–



Remove the rear and front lens caps and the camera body

cap.

• You can attach/detach the front lens cap in two ways, (1) and (2). When you

attach/detach the lens cap with the lens hood attached, use method (2).

Align the orange index on the lens barrel with the orange

index on the camera (mounting index), then insert the lens

into the camera mount and rotate it clockwise until it locks.

• Do not press the lens release button on the camera when mounting the lens.

• Do not mount the lens at an angle.

To remove the lens (See illustration



–



While pressing and holding the lens release button on the

camera, rotate the lens counterclockwise until it stops, then

detach the lens.



Attaching lens hood

It is recommended that you use a lens hood to reduce ﬂ are and ensure

maximum image quality.

Fit the hood into the mount on the end of the lens barrel and

rotate the hood clockwise until it clicks.

• When using a built-in camera ﬂ ash, make sure to remove the lens hood to avoid

blockage of the ﬂ ash light.

• When storing, turn over the lens hood and place it onto the lens backwards.



Zooming

Rotate the zooming ring to the desired focal length.



Focusing

When using the auto focus, the camera focuses the lens automatically.

When focusing manually, set your camera to the manual focus and rotate the

focusing ring while looking through the viewﬁ nder. The focus signal in the

viewﬁ nder indicates the current degree of the focus.

• The focusing ring can be rotated slightly past the inﬁ nity to provide accurate

focusing under various operating temperatures. Do not rotate the focusing ring

all the way to the end when focusing manually, even at inﬁ nity. Look through the

viewﬁ nder and set the focus precisely.

The values for equivalent 35mm-format focal length and angle of view are based on Digital Single Lens Reﬂ ex Cameras equipped with an APS-C sized image sensor.

Minimum focus is the shortest distance from the image sensor to the subject.

• This lens is equipped with a distance encoder. The distance encoder allows more accurate measurement (ADI) by using a ﬂ ash for ADI.

• Depending on the lens mechanism, the focal length may change with any change of the shooting distance. The focal length assumes the lens is focused at inﬁ nity.
