The CPL filter and FLD Filters are well made, I am fully satisfied and they really give good results. The polarizing filter is designed that you can "turn away" mirroring, very practical. The FLD delivers what it promises and brings more contrast and color intensity as well as heat into the picture. The lens hood has on the inside roughened matt plastic, which minimizes unwanted reflections. For users of a Canon 18-55mm Obejktivs That said, here a ring diaphragm and no flower is as necessary here that the front part rotates during zooming and focusing. Am very satisfied to the price gladly again.
