Carl Zeiss Jena Sonnar 120mm f2.8 Exakta with adapter works well on Canon EOS, 4/3 , micro 4/3, Sony NEX, fuji-X etc
Works well, no fungus , no haze ,aperture works, smooth.
Few short deep scratches on front, many cleaning marks on rear part, lens has lower contrast , otherways okay.
Such a rare piece, even in poor shape , nice addition to any collection.
