Wandered into the local brick-n-mortar camera store this morning and spied a mint-condition Tokina 100-300 f/5.6. My guess (based on the colors used) is late 70's/early 80's.
They let me take it home for a test drive. Not a bad lens. Walked around the back yard to test it for sharpness.
I'll need to do some more testing, but if it seems sharp all around I fancy I may just buy it.
