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 .–..) 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 (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 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.
