The filters are water resistant with the coating safely sandwiched between two layers of Schott Optical Superwite glass. These outer glass layers give the coating a scratch resistant protection rather than just a simple coating on the surface.

In addition to all the standard Firecrest features, we hand apply a special black anti-reflection coating to the edge of every Firecrest Pro filter. This coating helps to protect the edges of the filter but also control reflections and light leaks giving you ultimate control of your image.
