LENS CARE

• Although you should always keep the lens surfaces clean, rough cleaning

must be avoided. Wipe with a soft, clean cotton cloth moistened with

alcohol to remove grease or fingerprints from the lens surfaces.

If you use ether in cleaning the lens, a smudge sometimes appears on the

surface of a multi-coated lens. If this happens, wipe it again with a cotton

cloth moistened with alcohol.

• Keep the lens cap in place whenever the lens is not in use.
• Attach both the front and rear caps when the lens is stored separately.

• To ensure proper fit of the lens when stored in the leather lens case, set

the lens’ focusing ring to the infinity (°°) setting.
