• When using the lens in the 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.
• Tele-converters are efficient tools to add focal length to the photographer’s
telephoto lenses including zoom lenses but cannot be recommended for use with
wide-angle lenses or zoom lenses that cover wide-angle range focal lengths.
* When a tele-converter is attached, the focal length of the lens becomes longer but the
depth of field becomes shallower and it may be difficult to focus in AF mode. Therefore,
focusing in MF (Manual Focusing) mode is recommended when a tele-converter is used.
2X tele-converters cannot be used with this lens. Do not use 2X tele-converters.
• Certain camera models may indicate the maximum and minimum aperture values
of the lens as inappropriate numbers. This is inherent to the design of the camera
and not an indication of an error.
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 a 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.
• 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 a commercially available drying agent such as
silica gel, and change the agent occasionally. If you find mildew on your lens,
consult a repair shop or nearby photographic store.
• Do not touch the lens-camera interface contacts since dust, dirt and/or stains may
cause contact failure between the lens and camera.
• When using your equipment [camera(s) and lens(es)] in an environment where the
temperature changes from one extreme to the other, make sure to put your
equipment temporarily in a case or a plastic bag for a length of time in order for
the equipment to go through a gradual temperature shift. This will reduce
potential equipment trouble.
