This may be the wrong place to post this, not too sure. Anyway, I just got a Tokina 12-24mm f/4 (I am loving it by the way, if you have the money and are looking for a good digital super-wide, don't hesitate buying it; it's a wonderful lens), and I want a UV flter as I do alot of skating photography and I can already see the wheel or nose smashing through my precious lens; if it were unprotected of course. I currently work at a camera shop here in San Diego and we sell Bower 77mm "Japanese Made" UV filters for $24.99(not to mention I get 30% off ^_^), so it seems like a good deal. I tried it on my lens and after very closeinspecton, it seems legit, as there is no extra visible vignetting and the sharpness remains the same. Is this a wise choice to buy a bower, or should I save my pennies for something else?
