The bottom line: it is for photographers who want a permanent, color-neutral protective layer with excellent surface repellency and minimal added reflections. The filter is notable for its \u003cstrong\u003eMRC Nano coating\u003c\/strong\u003e that repels water and dust and for a thin, knurled mount that makes handling easier without adding visible effect to images.
