Cosmetic condition:  I would rate it at 6 or average  on a scale form 1 to 10.  Lens has been used but is in good condition. It shows light wear on the lens barrel from use. Front and rear glass elements are in good condition. Even though I see some scratches on the front. I see one larger 2mm and there are couple 1mm scratches form use. But they don;t show up in pictures, so damage is minor.  I don't see any scratches or scuffs on the lenses coating. No fungus or haze inside. Lens does not have any dust specs inside.  Glass looks good over all. 

 Performance: All lens features works good. Aperture blades are free of oil. Aperture ring clicks at every stop. Filter rim is in good condition. Smooth focus. Everything works as it should. Lens has been fully tested by my tech guys. I guaranty that it will arrive as described on your money back.
