Hi folks. Last year I invested some hard earned money and finally got myself a Leica. It's a M2 of 1966 vintage. I have 4 lenses for it now, a Summaron 35mm, Summicron 50mm f2 and a three-element Elmar 90mm of 1966 vintage, and also a Voigtländer 25mm snap-shot Skopar. I have been really pleased with the other lenses, but the three-element Elmar 90mm is not so good for color work (I rarely shoot B&W), as I don't really get the sharpness I want. Also the colors are somewhat subdued. Thus I am considering getting a sharp but affordable second hand 90mm lens with good multicoating and would like to hear some recommendations. I am not willing to invest more than 400-500 $ for a lens that I use least of my lenses (Summaron is #1 for me followed by Skopar). A Minolta CL 90mm has been in my mind, but what would you say?
