Thanks. I think I found the description. It's late. I'll try it tomorrow.

With respect to 'If anyone knows how to turn on magnification or focus
peaking with an MF lens I'd like to hear about it.' : The EM-5 has a
magnify command (which can be programmed to one of the buttons) which
will magnify the view when using MF lenses. Different from the AF+MF
setting when you touch the focus ring of an AF lens. I assume your EM-1
offers the same magnify command. The EM-5 doesn't have focus peaking, so
the magnify command is the only way to go for MF with legacy lenses.

Yes, manual focus all the way with an OM Zuiko 50/1.4. Yes, it's easy
to focus an OM Zuiko at f/16 in sun or subdued indoor day light. But
f/16 doesn't work in a dark hallway. As I said even the camera's
autofocus had difficulty there even shooting at f/6.3.
No, there is no "focus confirm" as on your DSLR adapter. The E-M1
employs magnification and focus peaking for MF focus assistance but,
AFAIK, it only works with AF lenses when in MF mode since turning it
on is controlled by the MF ring on the AF lens. You can, however,
turn on the 2X digital converter for a 2X display. Just remember to
turn it off again before you take the shot or you'll get the 2X shot.
If anyone knows how to turn on magnification or focus peaking with an
MF lens I'd like to hear about it.
When reviewing images already taken the rear dial can increase
magnification up to 14X. It would be nice to have that feature work
while taking images.

Yes, you can focus at f/16. I just tried it outdoors in bright sun and
various places in the subdued light in the house. Then I pointed it
down
the dark hallway going out to the garage. In the dark hallway I
could see
objects at f/16 but not well enough to focus until I opened to f/8
although
f/5.6 made focusing easier. Note that the camera was set at ISO 200
and I
didn't attempt to change that.
To give you an idea of the brightness ranges involved I fitted the
m.Zuiko
12-50 so I'd have 50mm available to go with the Zuiko 50/1.4 I used
for the
MF lens.
The outdoors shot was 1/320 at f/8 with -0.7 exp. comp. The indoors
subdued light shot was 2" at f/5.6 with -0.7 exp. comp. The shot
down the
dark hallway was 8" at f/6.3 with no exp. comp. f/6.3 is wide open
at 50mm
on the m.Zuiko 12-50. The camera had great difficulty focusing on
the edge
of a throw rug near the exit door. It took it several seconds to
lock in
and easily lost it. At f/6.3 on the 50/1.4 I think I could have
beaten the
camera and could have gotten an easier and faster shot by opening to
f/1.4.
Keep those old, fast Zuikos. They are still quite usable on an OM-D
body.
I would be less concerned about how easily you can focus a Zuiko at
f11 or
f16 than whether it could be done at all. I am assuming manual focus
all
the way. Is there some sort of focus confirm with the adapter you use?
(Not super critical for me, but nice to have.)
Thanks,
Joel W.
