Hi Johan, I had the M and the A50/1.4 and the M50/1.7. I can't really tell the optical difference between both 1.4-lenses, but the M has a better feeling for me (sold the M/1.7 and the A/1.4). One thing wasn't said yet: The M-lenses don't allow matrix-metering on the MZ5-N, and I think it is the same on the MZ5. So if you are thinking of getting digital (so am I) I would recommend to take an A-lens.
