Upload & Sell: On
It is not uncommon that sellers say their lens is "minty", and it has been used outdoors perhaps four times, and it has been sitting in their dry storage curio for some time unused.
Then, the date code places such sales pitch in a nice perspective, and sometimes additional clarifications start to surface about that "minty" lens:
"Well, yeah, the lens was made in 1999. No, I am not the original owner, I bought the lens off someone on eBay. OK, it is minty other than normal paint chips where the hood mounts, and the objective glass has a few spots with coating flaked off which doesn't affect image quality at all. And those white deposits on the MF rubber ring..... they should come off by rubbing with alcohol, besides, they do not affect the lens function, right ?"
