Vivitar 70-210mm f3.5 Series 1 Telephoto Zoom Lens for Pentax PK Cameras, cosmetically this lens is in reasonable condition, has a few light rub marks on the barrel of the lens and paint worn off of the aperture ring, the focusing and zoom mechanisms are smooth and the iris blades are clean and adjusting correctly, optically there are signs of fungus under the front element of the lens so ideally needs dismantling and cleaning.
