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 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 (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 or other
vehicles, boats, etc.
• Avoid subjecting the lens to rapid changes in temperature, otherwise
condensation can occur on 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.
• 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

the full open and approx. f/5.6 keeps light sources and other fuzzy
points perfectly round.

„ About the Lens Mount
The D FA lens mount is called
the “KAF - mount”. This lens mount
enables autofocus and
Be careful not to damage or dirty
the lens information contacts and AF
coupler on the mount surface of the
lens. Otherwise, failure or malfunction
may result.
AF coupler
„ 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.

Precautions When Using the Lens with a Built-in
• The built-in flash can not be used when the distance is less than 0.7m.
When the flash is used within 0.7m, it causes incorrect exposure
control and vignetting in the picture corners.
• If the built-in flash is used with the lens hood attached to the lens,
the flash light will be blocked by the lens hood. Always make sure
to remove the lens hood before using the built-in flash.
Screw the commercial 49mm diameter filter to the front of the lens.
• Since a filter becomes a part of the optical system when attached
to the lens, handle it in the same way you handle the lens with care
to dust, dirt and scratches.
• Use a circular polarizing filter with an autofocus camera for proper
exposure and autofocusing.
