Phoenix 500mm f/8 Mirror Lens with Mount - for Pentax Digital & Film SLR Cameras including ZX series, *ist D DL DS, K10D, K20D, K100D, K110D & K200D

I bought this on a whim because it was so large for so cheap. I'm still trying to find the best use for it, but I've gotten some decent images out of it. Used on my Pentax K10D, I find I get the best images out of it on a sunny day with a high shutter speed. I tried some night/tripod shots, and wasn't too excited about the results. Buy it for a cheap and lightweight lens to tide you over until you can afford one of higher quality.
