Seems in very good condition. Focus ring was stiff in one spot, but I've just took it to a camera technician who cleaned and serviced it. It is now much smoother and totally usable, although the resistance of the barrel is not exactly the same all the way as it would be on a new and modern lens. There is no fungus. I included several pictures to let you see the condition. The technician said the few dust particules inside the lens would not alter quality of image.  The last four pictures show the lens before it was cleaned and serviced by the technician. Let me know if you have any question and I'll do my best to answer.
