VIVITAR AUTO FOCUS ZOOM for NIKON
28-210mm 1:3.5-5.6 MC
This lens is being sold as-is. I've tried it on a couple of digital and film cameras and it works intermittently (both flash and aperture). The controls operate smoothly. Glass is unmarked and there are no signs or damage or abuse on the lens. The lens is very clean inside, no fugus and very little dust. The aperture blades are clean. It has a metal lens mount.
It is made in Japan and feels very solid.
