Olympus is providing their MTFs at 60 lp/mm, Pana at 40lp/mm.
The classic gang uses 30lp/mm ...
That is, of course, normal because the pixel density is (usually) higher in MFT land thus the lenses have to be sharper.
For 20mp FF you can still have fairly relaxed quality requirements. As we've seen with the EOS 5Ds R that approach may not hold though ...
Anyway, higher MTFs come at a price - which is one reason why some MTF lenses are comparatively expensive.
