To ensure long-term satisfaction please take note of the following tips for use and maintenance of your lens:
Before using your new lens, please read the contents of the instruction manual thoroughly to familiarize yourself with your lens and the proper techniques for creating the highest quality images possible.
When set on AF mode, be very careful not to hinder the auto focusing movements of the lens. Such interference may cause serious damage to the lens mechanism.
Avoid touching the glass element surface. Use a photographic lens cloth or blower to remove dust from the lens element surface. Always keep a lens cap on your lens when it is not in use.
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 circular movements from the center to the edge.
Use a silicon cloth to clean the lens barrel.
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 contacts of the lens-camera interface since dust, dirt and/or stains may cause contact failure between the lens and camera.
When using your photographic equipment in an environment where the temperature changes from one extreme to another, be sure to temporarily put your equipment in a case or plastic bag for a length of time to allow the equipment to gradually adapt to the temperature shift. This way you can reduce potential equipment difficulties.
