I bought this a year ago from the original owner and it looked practically new at the time, I've shot it quite a bit since then and it does show some mild brassing but overall is in beautiful shape. It's always had a filter on it and the glass looks clean and clear except for some micro dust inside as with any older lens. Focus is smooth, aperture clicks nicely. Comes with original box. I can't seem to find a rear cap but a front cap is included and the rear will be protected for shipment.
Love this lens but managed to find the Ais 1.4 and that lives on my F2.
And one of my favorites taken with this lens.
