The Tiffen Circular Polarizer is not multicoated at all. Multi-coating is a proprietary process, and we seriously doubt that any lens or filter manufacturer will tell you the exact nature and composition of their coating layers. Tiffen Digital HT filters are a state-of-the-art technological breakthrough in multi-coated photo and video filters.
Digital HT – High Transmission – filters offer the strength of a Titanium coating combined with the purest optical quality glass and Tiffen’s Academy-Award-winning ColorCore® technology. They present unmatched scratch-resistant durability and worry-free cleaning while other coated filters on the market today cautiously suggest delicate, if any, cleaning procedures, in fear of destroying the coating (and thereby the filter).
