I have tested my own old OM2 (serial 253621).
It will have the shutter open for 17 minutes and 20 seconds with ASA 12
film, gradually reduced to 8 seconds with 1600 ASA (130 seconds , 100 ASA)
In the "OFF" position the same logic applies, but the range is from 1/2
second to 1/250. (sensible compromises ?)
In the OFF position it will synconize correctly with flash if the exposure
time is 1/60 or lower, for some reason it will only use TTL Auto in the OFF
position with 25-100 ASA films (e g 1/ - 1/15), but with in AUTO
everything works.
