Thanks. Cool reading. :-) Many conflicting opinions. Overall sounds like a good thing to use...for protections, and glare reduction. I think I'll still use it in most cases. I forgot to ask how a UV filter would effect a polarizer when "stacked". I assume using a UV w/polarizer prob. doesn't effect the polarizing "effect". If I remember correctly, I think I read about special 2-in-1 polarizer/UV... by the way...not to be rude, but I asked if using a UV filter would affect saturation/color, not if it would casue flares and streaks. Thanks again...much appreciated . -Jeff :-)
