I had a feeling that would be controversial around here. Like saying coat hangers are just as good for speaker cables as $2000 oxygen-free cables in an audiophile forum. Lots of peacocks in photography, and lots of sunk costs.
Anyway for a film student on a budget the $10 Chinese UV protector models (e.g. Zeikos, Opteka, Maximal Power, etc.) are every bit as good as B&W and Tiffen. Hoya years ago _was_ the cheapie filter, but people realized that they were just as good as the fancy German ones (not to mention they make much of the glass for the rest of the industry anyway) and now they aren't so cheap. Of course some filters (of any price) may be damaged or just poorly done...and yes I've sent some of those back.
I have a huge variety of filters of various price ranges, all the way up to 4x4 Schneiders etc. And the rare moments I have a flare problem or something with a filter, I look down expecting to find it's a cheapie but there is my fancy B&W with all its multicoatings. When one has a problem with a filter, don't blame the filter, just unscrew it.
Anyway if you'd like me to set up a double-blind test of lens filters using the 35L or 135L or whatever lens you feel is worthy of trophy status, I'll be happy to do so, but we're going to be betting something that's gonna hurt or it's not worth the time.
