Jena Bm 2,8 / 120mm (Carl Zeiss Jena Biometar), 1961
The Biometar is an impressive (560g) long focal length portrait lens with a normal design. Its optical design combines the advantages of various lens designs such as the color purity of dual Gaussian lenses with the image sharpness of the Tessar types and the contrast of extended triplets. Thus, Zeiss created an alternative to what is now called painting reproduction. The result is a versatile mid-focal length lens without the often "dull" reproduction of many teleconstructions.
Because it was designed for medium format cameras, it has an extremely even distribution of sharpness and contrast throughout the image format.
Data: 5 lenses, aperture 4 to 22, angle of view 21,5 °, MDF = 1,3 m, filter thread 67 × 0,75, fixed Exakta connection with fully automatic spring-loaded diaphragm
