Igor, I used five different Nikon 50mm f/1.4 lenses over the years, from the pre-AI series that came with my Nikon F Photomic FTn to the AF-D version in the middle 1990s. All were excellent, professional quality lenses that I would put next to the best from anyone in the industry. The only 50s I've used that I felt produced sweeter results are the Leica Summicron-M 50mm f/2 and Contax/Zeiss Planar 50mm f/1.4 T*. The Pentax M, A, F and FA 50mm f/1.4 lenses were all good performers (the A, F and FA are the same optical formula) but not as good wide open as any of the Nikons I had.
In Nikon's current line, they have the manual focus AI-S and autofocus D series lens. I know these are optically identical and the differences are the mount and AF drive. The S series lens is new; might have different optics in addition to the newer AF mount with in-lens focus servo. I can't say what's different between them performance wise, but I would have no hesitation buying any of them.
