Professionals may find wrong with it, but for the connoisseur that I am (I use DSLR since 1974) these filters are fine for me. I wanted a UV filter to equip a new goal for my wife, and, considering the price, I tried buying these three filters. The result is perfect. For the "big pros" who find fault there that I will answer them, anyway, they all retouch their photos in postproduction, so ........ Small tip, I bought a collapsible rubber sun visor to equip the CPL filter, which allows to turn easily, being careful, however, to fold the sun visor for wide angle COs. With a long focal length you are left with a visor (unfolded) without preventing manipulate the filter.
