I recently sold my 50mm f1.4 Ai Nikkor. When used wide open on my D700 it was quite soft and hazy, highlights glowed like ghosts!
From the excellent tests online by Marco Cavina, it seems that the 50/1.4 AI favored resolution over contrast wide-open, while the previous 50/1.4 Nikkor-SC had more contrast wideopen (particularly in corners) with less resolution (center resolution indeed lower wideopen).
BTW there are at least two optical versions of the pre-AI 50/1.4 lenses, the switchover done around 1967.

PS - Marco Cavina, if you're reading this -- you're my hero!
i've had or used pretty much every Nikon F mount 50mm.
5.8cm f1.4 NKJ -great lens, but can be finicky
50mm f2.0 H AI -one of Nikon's best ever in my opinion
Agree with the assessments above.
I owned the 50/1.4 Nikkor-S and found it a good lens, now i have the Nikkor-SC which i have not used enough because i find the 50/2 more convenient. Also the S-C is a giant monster compared to my (insert superlative here) Canon FD 50/1.4.
On the other hand my old 5.8cm f1.4 Nikkor-S is... well i'd rather keep hush about this lens. Suffice to say that i will never sell it.
I also had the 50/1.8 AI with "long nose" design and it was probably the sharpest 50/1.8 or 2.0 lens I owned. But the rendering was too "harsh" for me for some subjective reason, so I sold it.
In my opinion the 50 is a useless focal length (too short to be long and too long to be wide) regardless of its image quality.
That's the idea, that's why it's a "normal" lens, for when you don't want to have neither wide or long-focus effects.
I found 45mm to about 55mm my most used FL. I would say 80% of my pics were made with a normal lens, and I own 45 SLR lenses, spanning the angles of view from 19mm to 300mm.
