Whatever you do, don't buy from that seller. I am the one who recently left the negative feedback. I bought a canon LTM lens from him. When I received it I found MANY deep scratches on the front element and asked him to OK a return, which he reluctantly agreed to. I sent the lens back and then did not hear from him for 2 weeks. When I finally got hold of him he refused the refund, saying that I had somehow changed the rear element and left white things inside the lens, and some oil on the aperture. It was ridiculous and I filed for a refund with paypal. He made up several stories along the way, all lies. I've never encountered anyone so resistant to take a return that they would rather have super negative feedback then to do the right thing. I got my money back, so paypal does serve a purpose in some cases. The seller fancies himself a lens/camera technician but I think he is probably a butcher. If you were to buy something, there's no way to say whether the lens had been opened up and closed with something wrong inside. Just a warning. Bob
