It is probably less important with later OMs unless you use Manual mode
often, but I always appreciated the shutter ring placement with the OM-1 as
you could readily see the EV relationship of shutter speed to aperture as
the full ranges are lined up opposite each other. It would have more obvious
if the aperture ring had been placed conventionally to make them adjacent,
but that could have brought the two rings into interference contact and I
suspect that Messrs Maitani & Co experimented long and hard before deciding
on that one.
The shutter ring round the lens mount emulated many of the leaf shuttered
cameras of a decade earlier and which also displayed the EV relationships,
often to the extent of coupling both rings together under an EV setting.
I've seen it stated that Maitani located it there to save space to make the
camera smaller, so it's interesting that he reversed the procedure - putting
a leaf shutter dial on top of the camera in the conventional place for a
focal plane shutter - to make room on the 35RC.
