Wayne, I always use a Circular Polarizer filter on both my lenses when outdoors. I like the way it cuts haze and produces the bluer skies. I haven't experienced any degrading of my photos at all.

I'd like to try a "nifty fifty" prime one of these days.

Would somebody tell me your thoughts on extension tubes for telephoto purposes? I hear mixed reviews. Do they force you to use manual focus?
