It started out as one of these, but got converted into more than fifty pieces by the time I was done with it. Here's a teaser image:
If you want the whole teardown with descriptions, I posted a Picassa web album of it, here:

Explains why these things cost so much money.
Cost me $105 but every now and then a good deal on eBay turns out to be a bum deal, and in this case, the lens had gone sloppy and soft from excessive wear and dust accumulation in the elements. I started to tear it down to see if I could clean some of the elements, but once I saw how badly some of the plastic bits were worn, I decided to go for broke (more or less literally). Enjoy
