To adapt the copal shutter, you'd have to do heavy modification and you'd
end up with something that looks like the bottom of an OM-2000.   Someone
may want to try it as a life project.

| Here's a question about shutters, probably best answered by John H. As I
| recall, he was once employed by Nikon. I remember the early Nikkormats
with
| the Copal shutters, and how amazing the 125th sync speed seemed.
|
| First, is there a particular advantage, other than sync speed, to the
| vertical metal shutter? Is there a particular advantage to the horizontal
| cloth shutter?
|
| Is there any way a vertical metal shutter could be installed in an OM3/4
| body without a complete, ground up redesign? Does it require more room in
| all dimensions?
|
| It seems that the only two current production cameras still using the
| horizontal shutters are the OM's and the M6, although one could debate the
| status of the OM's as current production, since they are probably just
| assembled from parts made years ago.
|
| As the debate about the future of the OM has continued here, I have
wondered
| if there are two things on paths that will soon intersect: the takeover of
| digital for all but specialized photography, and the day when Olympus runs
| out of major parts for the OM's. But that's another discussion.
