 The cheapest $US price I can find is $876.  The Leica 50/2 is $1995
and the 50/2.5 is $1295.  None of the Zeiss lenses are exactly
"budget" lenses.  The Nikkor 50/1.8 that you have often sung praises
of, that's a budget lens.  If you can direct me to the $600 ones I'll
buy a pile and on-sell them.

Have you tried a ZM 50/2?  Erwin says: "Now at last we have a lens
that equals the Summicron-M 50mm and is even a trace better in the
curvature of field area."  I found the same to
be true.  Its resistance to flare is much better.  I agree the
mechanical construction is not as good as a Leica lens, or as good as
the Konica Hexanon 50/2, which appears to me to be the best
constructed modern 50/2 for M cameras (the seven-element Summicrons
are the 'most built' ever, but they are all now approaching 50 and
optical design, glass making and other factors have come a long way
since then).

The flare in this shot with the 50/2 Summicron:
was what finally made me stop using my 50 Summicron.  It did it often.
 In extended use the Zeiss didn't do that sort of thing:
and neither did the Konica:

Some day when we catch up, I will bring a big pile of prints, all
three lenses (I still have them all) and a lens spanner so you can
pull them apart and have a look at how you think they're constructed.
