This is a Nikon AI 135mm f2.8 lens I purchased in March from ebay. The focus and aperture on this guy are great. When I received ith this was a minor coating mark on the rear element and a small scratch on the front element. If these things weren't there I would assuredly say this lens was never used before I purchased it. The barrel was clean but I put a couple scuffs on the lens hood. It's a great lens I just am not happy with the angle of view on this lens
