Yes, the first OM tubes were manual, not automatic. I would like to find
out when the automatic tubes were introduced.
I would also be interested to know why Olympus produced manual extension
tubes for the OM, when all of the lenses had automatic diaphragms (except
the original 20, 38 and 80 mm bellows macro lenses, which were not likely to
be used with extension tubes).
