Just got my Bronica ETRS today, my first mf slr. a real beauty, lens (75mm PE), body, wlf and film back looks brand new. I bought a slightly more used AEII prism finder also. The eyepiece diopter in it is a +0,5, and I can see in the manual from Butkus that they normally shipped with -1,5. The strength of my glasses are +1,5 , so how "far off" is the +0,5 diopter? If -1,5 is the norm, does +0,5 correspond to +2 in glasses?
