FED 1 Lens Type Information
100mm f6.3 Fed lens first made in 1938. Supplied with viewfinder less than 20,000 produced.
100mm f5.9 1937- 38 Fed lens, best used at f6.3 or smaller aperture.
50mm f3.5 Industar-10 copy of the Leitz Elmar 50mm f3.5 manufactured 1934-46 and fitted to most FED 1a, 1b, 1c and 1d. Old-style apertures f4.5, f6.3. From 1949 coated. From 1948 or 49 new international f stops, f4, f5.6 and so on. A four-element design. The most produced lens and even fitted to the next generation Fed 2 camera and supplied to China for fitting on Chinese made Leica copies - Dai Lai "Popular" (Fed 1 or Zorki 1 copy), Shanghai and Chang Chiang "Yangtze River" (Fed 2 Copy).
50mm f2 Fed copy of Leitz Summar 1938-41. A 6-element design with f2 to f18.
28mm f4.5 Fed wideangle lens 1938 -39. A 6-element design with f4.5 to f18. A viewfinder was produced in 1939 in very small quantities.
A number of 50mm f3.5 macro lenses existed.
Some time probably between 1947 and 1949 when the first KMZ Fed-Zorki cameras were being assembled at the KMZ factory in Moscow with the collaboration of Fed engineers the copy of the Leitz Elmar 50mm f3.5 was replaced by a copy of the Tessar 50mm f3.5 in the same collapsible mount. This probably happened due to technical information taken as spoils of war from the Zeiss factory, which was in the Soviet-controlled zone of East Germany. The KMZ version of this Tessar lens was the Industar-22.
The original Industar-10 lens manufactured between 1934-46 was a more or less exact copy of the Leitz Elmar 4-element lens that first appeared in 1924. This was based on the earlier 5-element Leitz Elmax which had been patented by 1920. The Industar-10, Elmar & Tessar had completely different focal lengths. The Industar-10s made between 1934 and 1948-49 were 50mm. Those manufactured after 1948-49 based on the Zeiss Tessar were 52.4mm. The later KMZ Industar-22 was 52.4mm. The Carl Zeiss standard is 52.4, the same as the Sonnar (Jupiter 3 & 8) and later the Industar 26M, Industar-50, Industar-61—all used the standard CZ focal length.
FED (& GOMZ) started using coated lenses as late as 1949-1950 (Maizenberg Book), KMZ (1947 onwards - Zorki Zenit camera line) probably never produced uncoated lenses because they continued the Carl Zeiss line.
Pre-World War 2 lenses have a slightly different lens-to-film register different from that of as Leica lenses. Consequently early Russian lenses should not be used on postwar cameras as they will not focus correctly, although results may be adequate when stopped down.
