PMFJI, as I know next to nothing about the Sony. I use adapters with
Zuikos on the 5Ds extensively. You're right about effect on focusing
without auto-diaphragm. I can focus pretty effectively through the VF to
f8 (in good light), though not necessarily tracking skippers. Brightening
of the image in the VF would be a great feature. I get this in LV mode on
the 5DmkII, but I don't consider that useful for the kind of shooting Dean
is doing.
I looked for a OM-NEX adapter with focus confirm and did not see one. I
find that useful in a general sense, though I realize that I have rarely
used it on the spate of focus-stacked images I've done recently (which are
pretty easy to focus by eye since they are shot at f4).
Can you actually focus a Zuiko at f11 or f16 on your E-M1? If so, that is
amazing.
Anyway, this seems like really good advice, especially if the NEX-7 has
that brightening feature in the EVF, and it gets me interested yet again in
the E-M1.
