[OM] Zuiko 1.2

[William Clark]

Does anyone know which of the 1.2 Zuikos were better than the other.  I have
the opportunity to get either a 55mm 1.2 or the 50mm 1.2 (the 55 seems to be
in better shape).  I plan on using it for astrophotography, so the 55 will
likely be better as it has a larger light gathering surface.  Any insight
(which one older, better coatings one one? etc....)  Also, which one may
have better collectors value?

Thanks,
-Bill
