According to one site I visit the OM20 and 30 were available in black as well as Chrome. I've never set eyes on either in black. Could anyone please tell me if they were available in black?
The unofficial Olympus OM Sales Information file says the same and, at least in the case of the OM30, shows both chrome and black versions.
I cannot recall personally seeing black versions of either.
OM20 come by relatively often in black. Don't know about OM30, but then again I never looked for one.
