I have the original Olympus 4/3 40-140mm f/3.5-4.5 SLR lens, which I really like. It was manufactured before the second series of 4/3 SLR lenses. So it does not have provision for contrast detect autofocus built in.
The question is, will it be able to autofocus, even slowly, on an OM-D? Or will it be manual-focus only?
These older lenses can autofocus in live-view mode on the more recent Olympus 4/3 DSLRs, but that involves some mirror flapping to use the regular E-series autofocus mechanism. But micro-4/3 is mirrorless and doesn't have phase-detect autofocus. So I doubt it can autofocus on the OM-D, but I'd love to be proven wrong.
Thanks!
