nice to know. ive been using nikons since the film days. havent checked others. I also noticed no one said Sigma filters (I think hoya makes for them and sell for cheaper) or B&W filters which are also very high quality. I like Nikon. I can rely on it. maybe a bit more than others but I have peace of mind. if I do need I will look into the new hoya HD. just so many sell them from asia and im very suspicious of them being counterfeit. and who the hell can tell anyway.
I've used numerous brands since the film days and some are definitely better than others. Who is making the best of anything can change any time in my experience and brand name is no longer the insurance it once was, I don't think, since leading technology can easily level, or reverse, the playing field. Some companies keep up, others don't and get left behind resting on their laurels. Nikon filters are on-par, I would say with Sigmas: Better than, say, a Tiffen, but not as good as a Hoya or a B+W filter.
When it comes time to buy just about anything kit-related my "insurance" against cheap knock-offs is buying from Amazon or B&H or Adorama. Period. eBay, as far as I'm concerned, could disappear from the face of the earth and I wouldn't even know it. I deal with those three vendors not only because I've always gotten good merch from the start but also because returns are hassle free and gawd knows I've returned some s--t over the years.
