Yeah, what Winsor said. But I don't agree with the offensive stuff,
since Olympus' point was that they were not depending on legacy,
"non-telecentric" WAs (i.e., OM Zuikos) to be a calling card for buying
the E-1. They finally (and wisely) gave in to the demand for the MA-1
(at least in certain enlightened countries), but that was a concession
to hard-core Zuiko-holics. And I think that decision has paid off.
