Wonderful collection!!!
Obsession? I bought these for studying the Cooke Portrait lens transitions.
Now I need to sell some of these for other ULF lenses though,
Keeping 15” f3.5 and 18” f4.5.

Quick definition: It's not a obsession unless it has cost you your home, family, or job. You have a fine collection there. (collection as opposed to a hoard).
