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.

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.
