Lens in Leica Threadmount
The FED 50mm collapsible lens
design was "borrowed" from Leitz Elmar. This lens appeared first on the
first FEDs in the 1930's and is was also known as Industar-10. In the
late 1940's this design was handed over to the KMZ factory and the Industar-22
The FED 50/f:3.5 design and appearance stayed virtually
unchanged for decades, but the optical parameters were constantly improving.
Restitution increased, coating appeared in the early 1950's. By the mid
1950's the lens was "finalized", and the later versions of the
lens are sharp and contrasty, well suited for black and white and color
The FED is of the same quality as the Industar-22
and Industar-50, and it was made exclusively by the FED factory in Kharkov.
This lens is the later version, which offers the
best optics and the best finish.
