I have heard this explanation too (not from Olympus), but it didn't
make much sense to me either.
If this is indeed the case, how can the Nikon D1 (the digital version
of the F100) be able to use all Nikon mount lenses? ie it doesn't
require special "digital" lenses.
Maybe "digital" cameras have an aversion to light rays that have
passed thru gorgeous hunks of real Zuiko glass - maybe the light rays
can only be detected by the CCD's after passing through a tiny piece
of cheap plastic.........
Seriously though, maybe some other list members could shed some light
on this issue. I'm still hoping for (one day !!) a replacement back
for my OM bodies that incorporates a 24x36mm CCD array that is
located where the film pressure plate goes. I know we've talked about
this before and many think it won't happen, but as far as I can see
the only thing stopping it from happening is the technical issues
(and therefore cost) of manufacturing quantities of CCD arrays to
this size, and similar issues with memory stick/card prices to hold a
decent quantity of such high res photos. There might be a challenge
to overcome with regard to OTF metering though - is the reflectivity
of a CCD array the same as film? Could the meter be recalibrated?
As the technology advances I think it will happen one day, as long as
one or more companies believe there is a demand and they feel they
could make some money.....

I just got back from the Seybold Convention and Expo in San
Francisco. At the Oly booth I asked about a digital body for all my
Oly OM glass. The answer was from a rep was, "Not that I know of."
"
He then went on to give a curious answer as to why not. "The OM
lenses do not work for digital imaging." He said that lenses
focused images by the rays crossing and the CD chip needed all the
light beams to be coming in on a straight axis because the pixel
receptors were like a cup and the light had to reach the bottom.
The present OM lenses land the images at an angle. I said,
"Hunh???" That was about all he was able to say. I said my
undergraduate course in optics must have been under different laws
of physics. It seems to me that exact parallel beams would only
exist in an infinitely small point at the center of the image.
