Selling my Vivitar Series 1 70-210mm f/2.8-4 telephoto zoom lens with a Pentax PKA mount.  This is the sought after "version 3" made in the Komine factory, confirmed by the 62mm filter ring and S/N 28614787.  Only a small fraction of these that still exist have the KA mount. This is a full frame lens and would be great on the new K-1 body.

Glass:  Clean and clear with minimal dust and no issues.  Minor dust specks but no scratches, no haze, no fungus.

Cosmetics:  Minor signs of previous use and wear as pictured, but overall very nice. 

Mechanics:  Aperture ring moves freely, focus ring turns smoothly, push/pull zoom moves smoothly, iris is snappy with oil-free blades, "A" aperture setting works properly. Zero issues and all functions work great.

Includes original Vivitar branded front cap and a standard rear cap.
