Carl Zeiss Jena Biotar 50mm
f2 in M42 mount.
Optically
it's very good. No scratches, fungus, haze, separation. Not much dust
inside. There are faint cleaning marks on the front element.
Mechanically
it's very good, focus works really nice and smooth, aperture works well. Blades are
clean.
Cosmetic condition is good, there is wear but not too much.
Comes with original front cap. (Disclaimer:
the plastic thing the lens is sitting on is just to hold the lens for
the pictures, not included).
