I know it is technicaly possible to put viewfinder from MZ-M to all MZ (i have MZ-5n) - but i'm not sure:
1) Is it useful ? 2) Does viewfinder (split-image central focussing area) show right focus with all lensen at all focus distanses (i don't use lenses longer than 135mm) - is it calibrated for all mz (5n) or only for mz-m ? 3) What is the size of split-image central focussing area compared to the spot metter area from mz-5n ?
