A soft, lintless paper specially prepared for cleaning lenses, filters and other highly polished glass surfaces; safe for coated lenses, too.
Careless "cleaning" can spoil the precision of a lens. Also, you can mar the reflection-reducing coating that is practically on all fine modern lenses. Tiffen Lens Cleaning Paper is your basic lens-care equipment.
Note: This is exactly the same product as Kodak Lens Cleaning Tissue except that it is under the Tiffen brand name.
