This is one of the very best wide angles ever made . The last version of the 21/2.8 made for Contax in Germany . Has been very expensive over the years and sought by alternative glass users . It has Sons Canon adapter and achieves infinity focus . A beautiful copy in near mint condition. Lens looks new and comes with leather pouch,caps ,adapter for canon and near new box.

These went for over $3500 a few years ago and you just could not find one. I am selling for 50% of that at $1750 net to me.
