I used the 1-7 a long while ago. It requires adjustment on OM1/2/Ns in
Manual because it is brighter than the standard screens. It is good
for slow telephotos, but less useful for wider lenses. You get a sort
of narrow area of brightness with the wideangle. I had only Vivitar
28/2.8, Zuiko 50/1.8 and Vivitar 80-200/4 when I used it so it must
have been the 28....
I think I still have it if anyone wishes to make a small contribution.

I haven't used one, but can say that the 1-7 does what you suggest for
long, slow lenses. It is much brighter than a 2-4 or Beattie on a
1000/11 lens and the central spot does not black out and gives the
same focus point as using a 2-4, but more easily. The area outside the
central spot is bright and clear, but does not focus (or one could say
is always in focus), so DOF (read none, at 1000mm) can only be judged
by moving the view around.

won't darken with the 24 and 35 shift lenses - is that true, or am i
reading
the chart wrong?
i know that it probably won't give DOF indications or correct manual
exposure, but i am interested in the clear field. is it brighter
than the 2
series screens?
