I guess it's got to make a difference in the real world, but I could not
see it in actual photos using a 50/1.8 loupe. Nor does MLU on the OM-1 make
any discernable difference that I could see over just shooting away.
It is still uncertain whether the diaphram stop down or the shutter is the
cause of vibration. I think it's the shutter. I taped the DOF button down
on my 200/f4 and put the aperture at f4 and was still seeing a pretty good
kick on the OM-1 from about 1/30 to 1/2 second (as evidenced by laser beam
reflected off the lens). There is virtually no movement with OM-2S using
the timer, so yes I'd say the electronic shutters were an improvement over
the OM-1. I don't know about the OM-3Ti, but it's a much newer camera than
the OM-1. I'd love to test one of those.
