filter's? Or a clear looking filter with the word Haze in it's description. Being brand spanking new to DSLR's and this site, I've been putting together an Rebel XTi 400D outfit and I've decided to go with the school of thought to protect my lenses by having a (protective) filter on each lense. I got one in a bag/kit and turned around and bought another...it says 58mm UV Haze. Did I mess-up?
