More than twice as expensive as a Hoya HMC UV filter, but much easier to clean (I do not know whether a B + W is not nano remuneration also easier to clean filter). In addition, you can see clear through the filter of the lens; the Hoya HMC you only noticed the colored filters, which in my opinion is not a good sign. (The filter adjusts the Fuji X lenses, although the opening of Gegenlichblende is very tight.)
