Summary: I bought this lens used. It was described as a used lens but in very good working order. The seller described it correctly and I have used it quite a lot since I bought it. It is a very good lens. I would buy from this seller again.
Summary: Before I bought this lens I knew nothing other than the reviews at Fred Miranda's very useful site. The reviews were good so I bought it. That was over 5 years ago and boy, this lens has delivered. Fast focus and amzing detail, contrast and color.
