Peter, I have only one Pentax UV filter, so I can't say. I showed samples of all three multicoated UV filters (B+W, Heliopan, and Pentax) to a collector who knows much more than I do. He and I felt that the German brands more free of coloring, but that the Pentax seemed to have the least reflection. I think B+W was the least yellow, with Heliopan second in clarity and freedom from reflection. The three brands were very close in quality; you can't go wrong with any of them. I favor Heliopan because they cost less than B+W and are the slimmest filters that are threaded in front. I have nothing against Pentax filters!
