Hello Don, Many many years ago, I was using an MX and switched over to the Nikon FM. Both had been purchased new by me. I had equivalent speed lenses for each and I don't recall there being a noticeable difference in viewfinder brightness between them. Mostly the Nikon was bigger and heavier and the match diode used 3 lights instead of 5. Very similar in operational style.
