The only problem I see with a third-party adapter is not mechanical. If the
4/3 system lenses use some kind of electronic information exchange with the
body, the body may expect or require seeing certain 'information values'
(e.g. voltages or resistances) to appear at certain contacts on the body
when a lens is mounted... Any adapter for OM to 4/3 lens mount would have to
'spoof' those values to some default "other lens" setting, so that the body
would know there was -some- kind of lens there, and the shutter, meter
readouts, etc. would work. Without the proper electronic handshake I suspect
the body will go into an error mode similar to the OM-4T with no lens
mounted... where the meter (and probably shutter in this camera) won't work.
Perhaps that is what the little brass pin is for, signaling the presence of
a lens mounted that otherwise couldn't make an electrical connection, so the
'spoof' will work.
I think Olympus will make some kind of adapter available, because it can
sell at least a body to some number of rabid, neglected, sensitive OM-users
who otherwise will be forced to abandon Olympus to go to Canon or Nikon for
a professional-level digital SLR system. I doubt Olympus is selling the body
at a loss to make money from lenses, so if they can sell you a body and
adapter first, they get some profit, while knowing you'll probably get at
least one lens along the line, and probably more eventually...
An adapter serves the telephoto-using market more than wide-angle, but I
think there must be more wide-angle and faster lenses coming up.
