This is a fantastic lens. If you're on this site, you know about it.
This is the cleanest copy I've ever owned, and I've owned 4. Glass is clean and clear, focus is smooth, aperture is perfect. Comes with front and rear caps, I believe they are generic, but I need to check later.
$195 shipped/pp'd to CONUS.
I also have a practically unused Contax - NEX adapter from rainbow imaging I can throw in for $10.
