hello everyone, im new to photography in the sense that i just pruchased my 30d w/ 17-85mm. i do not know what kind of filter i should buy for my lens. i know that its a 67mm filter but i dont know what brand or what "type" to buy. polarizer? netural density? uv haze? and what is clear protection? arnt they all clear? i dont know what each of these filters do and such so some help would be appreciated.
If you could, please suggest which filter i should buy for my lens. Somthing that if good quality but is a good deal or the bang for my buck.
Thanks to all who respond.
