Notes on use

• Do not leave the lens in direct sunlight. If sunlight is focused onto a nearby object, it may cause a ﬁre. 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.

• Do not hold the camera by the lens part extended for focusing, etc.

• 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 ﬂash use

With certain of lens/ﬂash combinations, the lens may partially block the light of the ﬂash, resulting in a shadow at the bottom of the picture. When using a built-in camera ﬂash, make sure to remove the lens hood and shoot from at least 1 m (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

1 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).

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

While pressing and holding the lens release button on the camera, rotate the lens counterclockwise until it stops, then detach the lens.

 Attaching the lens hood

It is recommended that you use a lens hood to reduce ﬂare and ensure maximum image quality.

20mm F2.8: Align the red line on the lens hood with the red dot on the lens, and rotate the lens hood clockwise until it stops.

28mm F2.8: Focus on something at close range and extend the lens hood out from the lens.

• When using a built-in camera ﬂash, make sure to remove the lens hood to avoid blockage of the ﬂash light. For the lens with the built-in lens hood, retract the lens hood back into the lens.

• If a marking (red line, red dot, etc.) is provided, attach the lens hood properly. Otherwise, the lens hood may interfere with the desired effect or may appear in pictures.

• When storing, turn over the lens hood and place it onto the lens backwards. (20mm F2.8 only)

 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 viewﬁnder. The focus signal in the viewﬁnder indicates the current condition of the focus.

Depth-of-ﬁeld scale

When focus is set on a subject, anything at that same distance will appear sharp, and anything within a certain range before and beyond the subject will also appear in focus; this is called depth of ﬁeld. Depth of ﬁeld depends on the subject distance and aperture you choose and is indicated by the lines on the depth-of-ﬁeld scale corresponding to the aperture.

• The depth-of-ﬁeld scale is for 35mm-format cameras. The depth-of-ﬁeld is shallower when you use Digital Single Lens Reﬂex Cameras equipped with an APS-C sized image sensor.

*1 The value for equivalent 35mm-format focal length is based on Digital Single Lens Reﬂex Cameras equipped with an APS-C sized image sensor.

*2 The value of angle of view 1 is based on 35mm-format cameras, and that of angle of view 2 is based on Digital Single Lens Reﬂex Cameras equipped with an APS-C sized

image sensor.

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

• 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 inﬁnity.
