Keep in mind the Tiffen filters that are used in the motion picture industry are probably not the same ones sold in the still photography market.

I have owned Tiffen and Hoyas in the past. Then I bought a B+W. They definitely are much better built. I have a Nikkor 105 2.5 that has a slight dent on the filter screw mount. I have trouble screwing Hoyas and Tiffens on that lens, but the B+W goes on nice and easy. They aren't too much more expensive than the other multicoated filters, so I personally chose those over the less expensive brands. My $.02.
