If you didn't have a filter then that stuff would probably be on your lens. I typically use a hood and a filter on all of my lenses. I make sure I buy the best quality filters, usually B+W. Logically speaking there is some inevitable degradation of image quality, but nobody has ever pointed any out to me, so as far as I'm concerned it's a non-issue.
