Tamron A020N Camera Lens User Manual


 
* When the built-in flash on the camera is used, adverse photographic phenomena
such as corner illumination fall-off or vignetting at the bottom part of the image may
be observed.This is due to the inherent illumination of the coverage of the built-in
flash, and/or the relative position of the flash to the edge of the lens barrel which
causes shadows on image. It is strongly recommended to use a suitable separate flash
unit 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.
