My aftermarket auto-extension tubes have worked flawlessly since they were
bought in the mid 70's. They don't have any makers marks on them.

Subject: Re: [OM] Introduction dates of macro equipment
All the macro gear except the 50/3.5 was originally manual. While you're
wondering, how about "why does the bellows have 1) a stop down lever and 2)
provision for the DCR when it was designed primarily for use with manual
lenses? Particularly given that the extension tubes were manual at the time,
and targeted at the only macro lens with auto diaphragm!
I guess the tubes were originally manual to save cost. The auto tubes are
quite nicely engineered, and I guess the margins must have been smaller when
they went to auto. Third party auto tubes I have seen have been nowhere near
as nicely made, but I haven't tried using them, and frankly, it's not a
large sample.. I'm sure someone else can say whether the oly tubes are
better - performing.
