Rob,
I've seen this shot of yours before, and indeed it is ugly. But
these OOF areas have an edge to them that is more defined and dense than
the inner surrounding area, more like a donut produced by a mirror lens.
No Nikkor or Pentax lens that I have has ever exhibited that. And if I
recall, you had said before that this was a 50mm Nikkor? I've got an
AIS 50mm F1.4 and an AF 50mm F1.8 and neither is close to being like
what you show here. To me, the 77 produces oval or egg shaped specular
highlights which are smooth and equal in density from edge to center. I
think they exhibit some coma also because their shape changes in
different parts of the frame. I've seen similar results from some Leica
glass. I guess some like it and some don't. In non specular OOF areas,
the transitions are very smooth, and there's nothing to dislike about
that by anybody.
Thanks,
Ed
