TO ENSURE LONG-TERM SATISFACTION
Avoid touching the glass element surface. Use a photographic lens cloth or a 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 fin-
gerprints or dirt on the glass lens surface with a rotary motion from the center to the edges.
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, dry place. When storing your lens in a lens case,
store it with commercially available drying agents 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 interface contacts since dust, dirt and/or 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 another, 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 though a gradual temperature.
This will reduce potential equipment trouble.
