I was reading leica-info and some people do share the same experience with me. I brought a mint non-asph R 90 2 and shot with it regularly. At 2 and 2.8, this lens is a bit too soft. Portraits at these apertures give me a feel of going to sleep. For those who like soft lens this is it. I sold it and now I am using R90 2.8 with happiness. It certainly reproduces images with a higher degree of realism and it costs less than 90 2. I also have apo M90 2 asph and I am certainly very much impressed by this lens. I doubt if Zeiss could go very much ahead with their new M mount 85 2 compared to the Leica counterpart. By the way, ASPH R90 2 is optically the same as ASPH M90 2.
I certainly agree with most of what Marc has written,in fact, I learned much from him. C-Y 70-210 is certainly very good. In terms of bokeh, it is like other Contax lenses which exhibits astigmatism. I published earlier in this forum that this kind of bokeh is also seen in G45 2. Other lenses which do not have this are C-Y 100 2 and the new Zeiss M-mount 50 2 Planar. Bokeh from these lenses are more pleasing. Astigmatic Bokeh looks like Van Gogh's work. He used parallel lines to reconstruct the face of a Portrait. You can certainly sees parallel patterns in astigmatic bokeh. If you like Van Gogh's work,you will certainly like this kind of bokeh. If someone wish to predict if a lens will produce astigmatic bokeh from the MTF graph, one can look for whether the two lines,one saggital and one tangential,divert or not. Those lenses with these lines staying nicely together gives the best bokeh. Those who wish to see photos on this subject could refer to my postings in this forum on G system,G lenses,Zeiss Ikon.
