Here's another oldie but goodie: a Vivitar Series 1 Zoom in 70-210mm f2.8-4.0. This lens design tested out as the sharpest of the 70-210mm Series 1 Zooms.
Condition of this one is 8 cosmetics, 10 mechanics, and 10 optics. It includes F & R caps, a coated 62mm skylight filter, and a hard leather(?) storage case. Nikon AIS mount.
This makes a great astrophoto or general purpose lens.
$85 shipped in the USA. Insurance extra. Certified funds or Paypal plus 3%.
Thanks and clear skies!
