I absolutely disagree with your regret regarding the OM-1.  This happens to
just point out a resonance with one equipment combination at a particular
shutter speed.  One of the few negatives of the OM system is that it is too
lightweight sometimes.  Heavier equipment has a tendancy to absorb or delay
the vibration long enough to not affect the exposure.

Instead of throwing out all the tests, I'd suggest that reshooting the
200/4 and any other questionable lenses with a later model OM along with
the OM-1 at various shutter speeds would be a good thing.  That way we
could determine just where the resonances occur so we can either avoid them
or treat them in an appropriate manner.

Chances are that there is a similar problem with some other lens/body
combination.
