I knew cheap filters could affect your pictures, but I honestly had no idea how much. I'm taking the crap UV filters I bought from Best Buy off my lenses immediately and getting some nice ones.

 Thanks for the link Brian. I've seen similar tests done. One of the best pieces of advice I heard awhile back.......if you buy an expensive lens with expensive glass in it, why would you put a cheap filter on it and risk adversely affecting your images.
