because ZF is designed for SLR
ZM is for rangefinder
but both SLR and RF are using the same size of film ....
I guess this should refer to MTF data...

For ZM lenses like D15/2.8, B25/2.8, B35/2, S85/2 etc the 40lp/mm line can reach or even exceed 80% performance
While for ZF lenses, only D21/2.8 and MP50/2 can nearly reach 80% for the 40lp/mm line
For Hasselblad lenses, the D40/4 IF and the FE 300/2.8 should be the best instead of Sa 250/5.6?
P.S. the 40lp/mm line should be the major indicator for micro contrast performance i.e. resolution
