Ok, I'm going to get around to adding my babies to the list.
I do question the value of the reflection color stuff. I had both SC and
MC examples of the 21/3.5 and 24/2.8 lenses. I peered deeply into them
side by side. The colors of the reflections were remarkably similar
within each pair. The marked difference between SC and MC was not color,
but brightness. The MC reflections were much less bright than the SC
reflections. I speculated at some length on the reasons why this would
be so in a prior post, if anybody is interested.
I don't see how this reflection stuff can be much use, since side by
side comparisons mostly won't be possible. Yes, green and magenta
reflections exist in some SC lenses (or perhaps I was hallucinating?). I
guess noting the ser# at which the old all yellowish reflections changed
to more sophisticated SC might be useful, but I wonder how accurate. The
current list has some lenses that are clearly miscategorized as to the
larger issue of SC or MC, whether through user error or front rings
switched when serviced.
