Funny, my problem with the 75 wasn't focusing - it was focal length; 75
is a neither-nor length - too tight when you want a 50, not tight enough
when you want a longer lens. I actually tested it out once and found it
only got me one of my steps closer to the subject, and that's not close
enough if I want to get closer than a 50 would bring me. So for me, the
85 is definitely superior, as is a 90.

Coming to the rescue of a favourite lens . . . !

No, and yes.  The AF 85/1.4 Nikkor has internal focusing, the AiS does
not.  The AF has nine elements in eight groups, the AiS has seven
elements in five groups (even if several Nikon sites say it has seven
elements in nine groups!?).  Clearly a different design.  The results
are very similar.  In extreme tests the AF has some colour fringing and
the AiS a little distortion and is softer at the edges.  Depending on
what you do the softness might be an advantage.  The AF is sharper if
you like taking pictures of little B&W lines and developing for
acutance.  People argue about this, of course.

None of this matters much in real life.  I kept the AiS, mostly because
it has a 'look' more like the Leica-M 75/1.4, which although I love it,
try as I might, I cannot focus consistently on an M camera.

If there is a difference between these particular Nikkor and Leica
lenses, it's _not_ in the bokeh.  The optical formulas are so similar as
to make the bokeh of this pair almost indistinguishable (shall we
conduct a test!?).  The real differences lie in the Leica having better
coating (making it less flare-prone and having slightly better colour
saturation) and tighter QC (meaning you're less likely to get a 'dog'
and that it costs three times as much).  Of course the Leica is a 75,
the Nikkor an 85.  As B.D. points out, that probably is the most
significant difference apart from the fact that the Nikkor attaches to
an SLR and the Leica attaches to an M rangefinder.

The Leica 80/1.4 R might be stellar too, but I never tried it because
I'm not a big fan of the R cameras.  The best of all the 85's may well
be the Carl Zeiss 85/1.2 but it has
a 1 metre close-focus and is like hen's teeth.  The Zeiss 85/1.4 is also

Now, let's all go find one of Kyle's posts and read the last line . . .
