Again, thanks for the nice notes - and for the perspectives. The various takes on this have been very interesting (and in some cases hilarious) to read, and I am beginning to wonder if I have developed gear deaccessioning syndrome (GDS).
Looking at the numbers again, the financial end of it is actually pretty insignificant in the grand scheme of things, apparently because only one or two of the lenses I targeted was worth more than a thousand dollars (and the fact that after January 1, some economies of scale will kick in that will more than compensate for the cost of the party). The other issue is not eliminating functionality only to have to reproduce it later. So it's looking like more and more of a disciplinary exercise - and probably not one that should be escalated into interpersonal conflict or resentment, as Roger says.
And having studied what is what, the only thing that is really duplicative is a Tri-Elmar (which duplicates four much less expensive lenses). So, roughly following the survey, I think I will eliminate that (11% by number of lenses; a much higher proportion by dollars) and keep the proceeds focused on photographic purposes (paper, film, scanner repairs). That fulfills the ritual bloodletting/hairshirting, serves a minor economic function, and preserves the zero sum nature of things. I think I will reserve judgment on the rest for now.
Regards,
Dante
P.S. Just as a side note, I'm not sitting on a ton of equipment of any type (a lot of what appears on my site is a collection of "exit interviews"). All of my M bodies and lenses fit in one small Pelican 1400 case (with the rigid padded dividers...). The rest, which takes up a Crumpler December Quarter bag, is not in question at all. That stuff is either used constantly, is impossible to duplicate in functionality at any reasonable cost, or was inherited.
