I didn't save the original post, I'll have to wait 'til the morning
to fetch it from the list archive, but... I thought (perhaps
mistakenly) that we were talking about an OM lens on an E-1 with
adapter, and whether its DoF markings [originally calculated for 35mm
film format] were useful, with or without conversion factor. If
that's the case, I still claim the DoF is different for a same-size
print (i.e., greater enlargement from the 4:3). Apologies if my
short-term memory is faulty :-( .
