I second the M35/2.And with a lot of luck (or at least a lot of patience), you can even get it for a little under that (as I did). I have this lens and must say I love it; it's probably my second favorite lens. My copy is razor sharp from wide open, and has a rather distinctive (in a good way) rendering (similar to pictures from the FA limiteds I've seen). Flare is the best controlled of any lens I've used. The bokeh is rather hit or miss though. On occasion it is nice and creamy, but sometimes it is really quite harsh (nissen bokeh) and frantic, in part as it's spherically overcorrected (the bokeh can also be a bit swirly/rushing wide open). Also, wide open, it can show some LoCA in the OOF areas It's also very small and light. Overall though, it's highly recommended.
