Pretty close except that the dark and light bit only occurs near the middle /
top with length of about 1/4 of image. Not right down the full image. Looks
like a vertical eye as its doesn't take up the whole pic. Although this
doesn't happen on all pics hence my leaning towards a power issue.
As for the om1n its out there and I'm lovin' it. Simple, reliable and 100%
trustworthy but an OM4 is an expensive paper-weight.

You mean something like this (where - is clean image, % is lighter, and + is
darkest):
-----%%+%%-----

With the proviso that I am no technician, that seems to indicate that the
first shutter curtain is slowing down in mid-travel, the second curtain
catches up with it after also slowing down before the first curtain then
accelerates again, and then resumes its intended course and speed, with the
second curtain following suit. I can't see what else could cause the
shutter slit to vary in width from normal, to wide, to narrow, to wide, to
normal.
Perhaps there is a mechanical obstruction somewhere?
Get the OM1n out Craig!

Incidentally some of my photos are displaying a dark vertical patch (middle
only) and around this an over-exposure patch which makes it kind of look
like a vertical eye. The rest of the photo is ok.
