I prepared review 50-2 Industrial and traditionally take pictures of the lens. Photos this time I made two lenses: Cosinon 55 f2.1 and Carl Zeiss Jena Biotar 58mm f / 2 This little test I think shows why I appreciate the old Zeiss lenses. At the same time on a normal image without magnification Cosinion is not a bad lens.
