This is the first I heard mention of a non auto tube from Olympus, except
that I have a 7mm non auto that I picked up with a 25mm auto, from an Oly
bin at a camera store.
Am I correct in thinking that the non auto tube will create less vibration
than an auto?

I have a set of non-auto Zuiko extension tubes (7, 14, 25). Found them on the
web. They're not quite as convenient as auto tubes but at $15 who can
complain. I suppose there's less vibration but is it in any way significant?
This is a valid question, by the way.
