In my case, I've made the problem worse by using a 1.25X magnifier at the same time.
It gives a 1:1 view of the world, so I can look with both eyes open. So, basically my M7 0.85 becomes a super M3.
If I use 35mm, I have the Summicron (8 element) with the M3 finder goggles. It makes use of the 50mm frame line. This is perfect if I don't use the magnifier. If I use the magnifier, I still have to roam around a bit to see all the edges.
Without the 1.25x magnifier, I find the 35mm frame lines too far away for use with glasses on. It is virtually the entire finder. I do have a 35mm CV external finder for such occasions. As I said, it's basically like an M3 finder.
The benefit is at the 135mm end, where the 0.85 finder kicks butt!
