Thanks, C. H., for your efforts in showing this on different lenses. I've
been watching this, in your tests and in some I did myself a month or so
ago.
I see that bokeh is not an on/off thing (large chorus of duh! here). I think
we are fortunate that, although no Zuiko is absolutely stop the presses over
the top creamy, neither is any world breakingly bad. If it is on a scale of
one to ten, I think Zuikos mostly range from 4-8.
I did notice in my own tests that the lenses over 50mm are better than the
shorter ones (another Duh! chorus). The one thing that I noticed (testing
85/2, 135/2.8, 200/4) is that the 200 was quite good, at least a 7.5. the 85
and 135 were at least as good as any other tested.
I didn't have as big a problem as you with the 28/2 (I found it to be in the
"not unacceptable' range), but I agree that the 21/2 ranks highly. The
50/1.2 gets weaker the closer the focus, and the 50/3.5 leaves a lot to be
desired. My 35/2 is generally average. I saw nothing special in my early
35-70/3.6 early version, and it remains for sale.
The biggest difference I noticed was in my Nikkors (all early late
sixties/early seventies classics) had noticably poorer bokeh, confirming
what I had read. Perhaps the Zuikos benefit from a different designer's
goal.
