The Aspherical-marked lenses and green-stripe FL / FD Fluorites in my collection are keepers...more ordinary things like
24/2.8, 28/2.8, 50/1.8 could easily go unmissed. All F-1s stay, all Canonflexes do too, and the T-90 'til it belly flops! Okay, I'd keep that oddball, meterless FP with its accessory prism-top meter too.
Is there any reason to have a pair of ODF-1s???
