Dr. ISO is traveling but I don't think manual mode is affected per se
as the cam of course operates on what the "true"
ISO actually is. IIRC Canikon/Sekonic had been on the same page in the
past. One might have to experiment with an external meter
wiht the OM-D to see how the exposures behave and how best to so so in
a given situation. Perhaps much less relevant if a good live raw histo
were available.
some stuff on meter calibration: Minolta was on a slightly different
page

ISO "standards" certainly don't seem standardized, Mike
