The glass is in pristine condition. I have not spotted any of the photos using Photoshop. Any marks on the glass is surface dust. I bought it from Ffordes last year and have used it sparingly since. It produces great results as a portrait lens and focuses down to 1m. It is considered by many to be the best lens in the Zenzanon-PS line up for portrait photography. There is a small scratch in the rubber grip of the barrel. It was there when I bought it from Ffordes, most likely a scratch mark from a stray darkslide or the like. I'm asking £350 for it plus £20 international tracked shipping from Sweden. Also, I'm selling an adapter for Canon EOS, which adapts SQ lenses to fit Canon EOS. In perfect condition. Asking £30 plus £10 international shipping. Will cover all shipping costs if both items purchased together.
