Shiny new lens

For the past year and a half I've been trolling kijiji for lenses for my Sony dSLR's. It had been a week since I'd last looked when I loaded up Kijiji and found this lens.  Looks in mint condition. Owner sold it because he hardly ever used it.  I doubt it would be a lens I would lug on a 3 hour walk. However with tripod outside my window this lens sounds like a winner.
