My top contenders, in this particular order, are the Olympus 35 SP, Canonet QL17 GIII, Minolta 7sII, Agfa 1535 (per Huss's usual excellent recommendations), and the Konica Auto S3. I'm not worried about the size of the camera. (Coming from large and medium formats, all 35mm cameras are tiny to me, haha.) The lens is, by far, the most important thing to me.
It's really tough choosing between these five since they're all excellent (as are the other ones I mentioned including the Yashicas).
I guess the real question is, which of these has the very best Leica-like lens and which one - if CLAd properly- has the best internal light meter?
