So first of all the great thing about these filters: they are simply EXCELLENT !!! Almost no colorimetric drift, no loss of sharpness, no aberration.

82mm? I have some lenses that I can pick up two of and not be 82mm in size! So, when I needed a UV filter for a new lens with this giant filter size, I came straight to K&F Concept. I wanted to be sure that the threads were precise, that the glass was top quality, and that the coatings eliminated filter-induced flare while resisting dust and smudges. As always, K&F Concepts quality tops the competition. I also wanted a CPL for the new lens, so finding the two filters in a kit was a bonus. The polarizer is low profile, threads on properly, turns smoothly, but holds its orientation without drift. Again: Full Marks!
