CLEANING & STORAGE
Blow away any dust or debris on the lens (or use a soft lens brush).
To remove fingerprints or other smears, clean with a soft cotton cloth
rubbing in a circular motion. A “microfiber” cleaning cloth (available from
camera or computer retailers) is ideal for the routine cleaning of your optics.
For a more thorough cleaning, photographic lens tissue and photographic-
type lens cleaning fluid or isopropyl alcohol may be used. Always apply the
fluid to the cleaning cloth – never directly on the lens.
For extended periods of storage, store in a cool and dry environment to
avoid any damage to the device.
