This lens is functioning 100% as it should be although there are 2 things to note, the 4th picture shows a small chip at the very edge of the front element, I have tested this lens on a film SLR and a digital mirrorless and the chip does not affect the image quality. The second thing to note is in the 5th picture; there happens to be a very small splotch of fungus on one of the internal elements. Once again having testing the lens on both a film SLR and mirrorless camera, I could not detect any noticeable affect to image quality. Other then that the lens focuses and zooms like butter, and the aperture is smooth and precise. If you happen to have any questions of concerns please don't hesitate to send a message.

Happy Bidding!
