The Multi-Coating and water repellent is both for flare protection as well as a protective surface. Polaroid Pro Series UV filters are constructed from high quality German Schott glass and features a ultra slim filter ring.
I have bought several of these. One for each of my Fugi lenses. They seem to be very good quality and they are so thin you can hardly tell they are mounted on Lens. You can hardly read the writing on them.
Yes I would highly recommend these filters.
