So I'm considering getting a UV and a circular polarizer filter... About the UV filter, should I just get a basic one, that does nothing but protect the lens? Or is it worth it to get a fancier one... like one with Haze/multi-coating? Mainly I want to just protect the lens and keep it on all the time, but if I can get other benefits (and hopefully no trade offs) I wouldn't mind paying a bit more. As for the polarizer... how useful are these if I just want to take hand held shots outdoors? My concern would be that since they stop down your exposure, you'd need a tripod to hold it still to compensate for the slower shutter speed. Thanks!
