I have seen this subject mentioned, and even debated, elsewhere. Thus, as I am considering adding an FM2n, I thought I would query the APUG 35mm panel experts. I have read that the 1/4000th and perhaps even the 1/2000th speeds are fairly inaccurate. I recall reading that the 1/4000th setting really fires at about 1/2750th. Has anyone heard this? Can anyone confirm, deny...or discuss? I really like my FE and FE2, and I would not want to be disappointed with the FM2n.
