This is the Nikon NIKKOR AF 50mm f1.8D. Great lens for the price. I have a Canon 60D and am upgrading to a Sigma 50mm f1.4 canon mount so I am looking to sell this. No trades unless you have the previously stated lens.Condition is like new. I have had it for a year, used it for cinematography. Comes with both caps, original box and manual.Serious inquiries only.Thanks.
