This topic of 50/1.4 S/N's keeps resurfacing. I have three "MC" 50/1.4
lenses. One of them has a S/N <1M, and is decidedly different from the
other two in coatings, although it is an MC. The other two have S/N
1,055,### and S/N 1,112,### puting them on each side of S/N 1.1M. Their
front rings are marked with:
1,055,###: "ZUIKO MC AUTO-S"
1,112,###: "ZUIKO AUTO-S"
It is obvious the second one was made after Olympus stopped marking their
MC lenses with "MC" and the newer one has a pair of fixed tabs on the back
to protect the rear element. The older one has a single, rather wide tab
on the back for the same purpose. That and the front ring marking are is
the *only* differences I can tell between the two. There is *zero*
detectable difference in element/group coatings and performance. Indeed,
there is very little difference between performance of these two and the
third one with S/N < 1M.
IMHO, performance among the 50/1.4 MC's is affected much more by condition
of their glass, focus helicals and barrels.

114 definitely is. 108 is likely. I had one that was 108x but high, like
1088 or 1089 (don't remember) and I'm sure it was the last series.

OK everything over #1.1M is the desirable version for sure. But wasn't
there some discussion that the actual cutoff was between #1.0M and 1.1M?
I now have a #1080xxx and wonderered which side of the fence it's on?
Anyone know how to tell?
