Please note: My late husband was a professional Photographer and I am selling his cameras, lighting and other photographic equipment etc. As I do not know very much about photography and unfortunately never took any interest in it, I am unable to give any information about condition or workings of the cameras, lenses etc. All I know is that he spent hours looking after them and he kept them in excellent condition. According to his notes was this lens in Very Good condition!
Please accept my apologies for the inferior quality of the photos, but I am no photographer (as you can see)!
