Camera has: 1. Full P program. 2. "Shift" Program, that is
shutter-priority. 3. aperture-priority with "conventional" OM lenses
(Zuikos).

Yes, one has to use AE lock for achieving a kind of compensation. Too bad.

The grip is needed for loading the batteries; there are two kinds of it,
100 and 300 (with flash); both are classifieds as "accessories", but you
must use either one or the other. MD is built in the camera. Of course no
other Motors or Winders can be used.

Yes, it is very bright compared to 1-x screens.

And also common (manual or auto) flashes. F280 works in super FP mode with
AF lenses only. I use a Vivitar AF flash (with a bigger IR and R emission)
on it.

It is strange you can't use a C-Pol filter (yes, Olympus says you cannot),
I think you can use Pols in MF mode. And of course you can use Bellows and
"big" lenses with an extension ring.

No other manifacturer released an AF camera with same screens and same
drives than MF ones. FI Nikon users need differend drives for: F, F2, F3,
EL, FA-FE-FM, FG, EM. That is 7 at all different kinds of drives, none of
which is compatible with AF (Fx, Nxxx) cameras. And the screens situation
is only slightly better.

I expect a new OM AF camera with the same (or better) AF performance as the
recent IF cameras. My opinion is this: Olympus should release the two IS
cameras (also) with interchangeable lenses in OM AF mount. And should
release the 28-110 and 35-180 zooms in both "conventional" and AF OM
mounts.
