Dreaming with full Technocolor, I wonder how much it will cost to make such
a adaptor for small runs. The OM-EOS adaptor is around $200 and it is
purely a machined part. Would $500 do it?
Would you pay $500 to use your Zuikos on the new 4/3 systems? Lets say 200
get sold, that's a revenue of $100K. Is that a big enough draw?
With a 2X multiplier, the thought of a 500/2 sounds really amazing :-)

one could design an adaptor that does the stop down automatically - after
all, the digital lenses have to be stopped down as well. Even if this is
done by a motor / actuator assy in the lens (like focussing on almost all
modern AF lenses) the adaptor could provide that functionality (as well as
encoding the mechanically provided f-stop selection the the digital body).
After all, what are we looking at, functionality wise:
3 things:
-Mount / Unmount OM Lenses - purely mechanical issue
-Transmit selected f-stop to body - probably mechanical to electronic
conversion - doable
-Actuate aperture stop down lever from body (probably electronic to
mechanical conversion - depending on f-stop actuation design of new
digital lenses could also be mech-mech connection) - probably the most
difficult if we are looking at mech-mech, but I'd still say doable.
(Btw - did you notice on the picture I had linked in an earlier post that
there seem to be some buttons on that adaptor - could be to select the
biggest available fstop on some lenses so the electronics of the body know
what lens they are dealing with)
