Wayne,
I think yours is an interesting idea. Would there be
someone from the List who can perform these types of
analysis or had access to a lab that could do it? What
would be the cost to be expected for spectroscopic
analysis?

I reckon if enough members (how many list members are
there, Thomas?) each donate say $5 to $10, we should
go ahead and purchase a lens to sacrifice. I'd
certainly be willing to spend a small amount to learn
what the 1.2/55 being the "state of the art" (as I
understand) in 35mm optics in that era was actually
made of... :-)
