Very good condition! Little cosmetic scuffs and brassing on the metal, customary for an old m42 lens from the 1960s, but this thing is built like a tank! Light and pretty small for such a long lens, too. The aperture ring turns smoothly, so does the focus. Front and rear elements are free of scratches or marks, no internal dust, no fungus, no oil on the blades, no balsam separation. Use on your old 35mm or get a cheap adapter and mount on your Canon or Sony!
