This lens was part of a lot of camera accessories that came from the estate of a photojournalist. No testing has been performed on this lens. The lens shows no issues to be of any concern and the manual levers all operate normally. There may be some areas on the body where the metal finish may have scuffs on the black finish surface which would be from normal wear and tear and to be expected with an item of this age. Use the information and the photos to decide if this is suitable for you.  The photos are part of the description. The lens is being sold as is as seen in the photos with the leather caps and the covers. Ask questions if you need more information before buying.
