Additional information:

The Carl Zeiss Jena Flektogon 50 mm f/ 4 is a wide-angle lens with the P6 (П6) lens mount   for the Kiev-6/60 and the Pentacon Six cameras.

Angle of  view°78°

This is a good wide-angle lens for the К-6 system. There is no distortion. The image is flexible and sharp.

The Carl Zeiss Jena Flektogon 50 mm f/ 4 has the following drawbacks: side light is not handled well, huge screw mount diameter for filters, weight and dimensions.

It can be easily mounted on modern SRL and mirrorless cameras by means of adapters.

 

The Carl Zeiss Jena Tessar 50 mm f/ 2.8is a kit lens for the Pentacon Practica cameras produced at the Carl Zeiss in Jena.

It came in the two variants body variants, black and "zebra", the "zebra" version appeared earlier. The two variants of the lens differ in color, marking, aperture control and minimum focusing distance (the "zebra"  enables to focus from the distance of 35 mm., as opposed to the later black lens).

The lens is based on the classic Tessar scheme elaborated by Paul Rudolf and patented by the Carl Zeiss company in  1902. It was produced in large quantities, outnumbered only by the Soviet Gelios-44 lens.  Alongside with the Practica camera, it was a dream of a great number of Soviet photographers.

Its almost complete analog is the Soviet Industar-61 L/Z 2,8/50, they differ in  the aperture drive functioning and sharpness (the German lens is sharper).

The Carl Zeiss Jena Tessar 50 mm f/ 2.8 lens is made of steel with aluminum aperture dial and focusing rings. It is equipped with a 5-blade instant-return aperture, a tumbler for a depth of field preview, and the m42 screw mount
