User Manual

provided by the camera manufacturer for all flash photography.
When using the lens in a telephoto focal range, it may be necessary to use a tripod to
avoid camera shake. Using high speed film (ISO 400 or faster) with a fast shutter speed
is also helpful to reduce the influence of camera shake.
Do not forcibly turn the focusing ring when the lens is set in AF mode. Doing so could
damage the lens and/or camera.
Certain camera models may indicate the maximum and minimum aperture values of the
lens as approximate numbers. This is inherent to the design of the camera and not an
indication of error.
Please be aware that there is no infrared index line on any models listed in this owner's
manual. Therefore practically no black and white infrared film can be used on this lens.
TO ENSURE LONG-TERM SATISFACTION
Avoid touching the glass element surface. Use a photographic lens cloth or blower to
remove dust from the lens element surface. When not using the lens, always place a
lens cap on it for protection.
Use a lens cleaning tissue or lint cloth with a drop of cleaning solution to remove
fingerprints or dirt on the glass lens surface with a rotary motion from the center to the
edge. Use a silicon cloth to clean your lens barrel only.
Clean the lens barrel with a silicon cloth. Do not use benzene or paint thinner or other
organic cleansers.
Mildew is an enemy of your lens. Clean the lens after shooting near water or in any
humid place. Store your lens in a clean, cool and dry place. When storing the lens in a
lens case, store it with commercially available drying agent such as silica gel, and
change the agent occasionally. If you find mildew on your lens, consult an authorized
repair shop or nearby photographic store.
Do not touch the lens-camera mount contacts since dust and/or dirt stains may cause a
contact failure between the lens and camera.
When using your equipment in an environment where the temperature changes from
one extreme to the other, make sure to put your equipment temporarily in a case or
plastic bag for a length of time in order to go through a gradual temperature shift. This
will reduce potential equipment trouble.
