Hope it's ok to revive this thread.
I do a lot of driving for work. After looking through the "prime, prime, everywhere a prime" I started allowing myself some extra time to stop in thrift/pawn shops if I come across one. Now it's kind of become an addition and I have to give myself a LOT of extra time - I blame pepperberry farm
What I've found in the last couple of months:
$5 - SMC Tak 55/1.8 Focus ring wouldn't turn. Had to remove the broken distance scale and clean/lube. Otherwise in good condition.
$30 - ME Super w/M 50/2 and Vivatar 135/2.8 Auto Telephoto Close Focusing. Both lenses in great shape except for a small amount of fungus I had to clean from the 50/2.
$5 - Tamron Adaptall-2 80-210mm f/3.8-4 (103A) Very clean.
$10 A 50/1.7 Had to fix the aperture ring spring. Otherwise great shape.
$12 Tokina RMC 28-70/3.5-4.5
My favorite so far is the Vivitar Close Focusing. Splitting the bundle evenly I call it $10.
