When Olympus dropped 'MC' and left only 'Zuiko', they changed something
else:
my silver nosed 35mm/2.8 reads: AUTO-W 1:2.8 f=35mm
while my newer 24mm/2.8 reads: AUTO-W 24mm 1:2.8
So they changed position and deleted 'f='. Now I think they only did this
with (black nosed) MC lenses.
Therefore, I think that any black-nosed Zuiko with first the mm's and second
the maximum aperture without 'f=' is multi-coated.
Anyone who has information that this is no valid assumption?
