Bruce, Olympus took a lot of care that every Zuko lens offers the same high
(not highest) performance level.
In a prospectus from 1980, Olympus wrote that it would not be possible to
distinguish the 28mm F/3.5 and the 28mm F/2.0 when you compare their shoot`s.
Sure, the faster a lens is the more difficult it get`s to reach a high
performance level.
I like the Zuiko-lens-line to demonstrate this, when you compare the increasing
amount
of optical elements when the primes are getting faster and wider.
I know, I`m also a testing guy, thinking too much about lens qualities.
Maybe this is because the first Zuiko I owned was a SC 1.4/50.
And the fist test I read were about this lens too, and its results were (not
that bad), but
somewhat poor..... :-(..... So the reserach went on, because I already owned
some more
Zuko`s and achieved pleasant results...???
Maybe there are situations when the faster or slower version might have an
advantage, in
respect to... but in most cases they should not as relevant to be visible in
the result.
Take your favorite Zuiko, or the one most appropiate to the situation, and
enjoy it.
