This is the latest version of the 50mm sumicron. The box evidences its vintage at Feb., 2008. Six-bit coded with box, instruction manual and Certificate of Inspection. I believe these come with a three year passport warranty but do not have the warranty papers. I am the second owner. Not a mark on the lens body or glass. Very sharp lens optically - a gem. I am asking $950 delivered and paypalled. 3% discount for e-check. email is [email protected]
