M3 single stroke, from 1960. It's all I can afford for now, and I love it. I use a Voigtlander lens for now, the 35 2.5 color skopar, which is actually pretty good considering the price. Going to get a pre-ASPH 50 Summilux soon, and a 90 Summicron or Elmar, depending on prices. Then hopefully getting the new Voigtlander R4A sometime, and a 21 4.0. My second M body (it's inevitable) will probably be a black M4-P, then eventually a Noctilux.
