Where I struggle with the 50N is that its formula is the same as the C/Y 50 F1.4, and I wasn't too excited about that lens. Another option is a used 50/1.4 ZE, but I had that lens too, and again, its bokeh could be, lets just say not so good.
Hi John-
Using both the N50 and the c/y50, I am convinced that they are not the same "optical formula". No doubt that they are very similar. I suspect that there are differences in glass formula, not to mention barrel design, and possibly other subtle changes that overall has proved the N 50 with (in mt experience) sharper performance across the frame, better contrast, flare resistance, and nicer bokeh. I was some what surprised, because I originally viewed them as "the same". Maybe it is just my samples of these lenses, but my c/y 50 performs as well as any other copy I've seen. I have come to the conclusion, however that they are not the same and the N 50 represents a clear refinement of the earlier c/y lens. The ZF/ZE 50 is different again, subtly but noticeably warmer than the Contax 50's with a somewhat different look wide open. Other than color, it is hard to tell these lenses apart by f5.6 -- but that is probably true of any group of quality 50mm lenses. Of the 3 Zeiss 50/1.4's that I have (N, c/y and ZF), the N is the one that I am going to keep. Of course, the ZF/ZE 50 MP is another story, and if you don't need f1.4 it is clearly the choice among all of them -- I am really pleased with my ZF 50 MP.
