Jupiter-3 (Kiev)

                                                                                                

PT2005. Seems to be an earliest version of "Jupiter-3" lens. Under initial name "ZK" ("Sonnar Kransogorsk"). Very few lenses released by KMZ in 1948-1950. These first samples are totally assembled from Zeiss (Germany) optical glasses. Focal length - 5 cm (5.2 cm), aperture range f1.5 - f22. Focusing range from 1 m to infinity. Number of elements/groups: 7/3.  Angular field - 47º. Kiev (Contax) mount. An earliest so far known lens has s/n #000949 1948 (Ilya Stolyar coll.).

 

 



 
 

PT2005 - ZK 1.5/50 mm  #000949.

 

  

PT2010. 2nd generation of these beautiful lenses. Almost identical to its predecessor "ZK" (slightly changed body design), but under name "ZK Zorki" already. Very limited batch of these lenses released by KMZ in 1949-1950. Partially or totally assembled from Zeiss (Germany) optical glasses. There are no KMZ logotype on these lenses (old KMZ logotype on PT2005 lens). Date prefix in the serial number already. An earliest so far known lens has s/n #492091 (Molotok 2012).







Lens #492100 opposite from Ilya Stolyar (USA) collection.

PT2015. An ultra rare version to find. Released in 1950, but under old name "ZK 1.5/50" again. New KMZ logotype, date prefix in the serial number. Very heavy lens! An earliest so far known lens has s/n #5000015 (Ilya Stolyar's coll.).


 

 



 

PT2015 - ZK 1.5/50mm  #5000015.

 

  

PT2020. Lens almost identical to PT2015, but under regular name "Jupiter-3" already. With "ears" for diaphgram settings yet. A limited batch of these lenses released by KMZ in 1950-51. An earliest so far known lens has s/n #50000839 (Ilya Stolyar's coll.).


 

 



 

PT2020 - Jupiter-3  #5000839.

 

  

PT2025. Seems to be an early version of regular Jupiter-3 lens. Released by KMZ in 1951-1956. No more "ears" for diaphgram settings. Signally changed body design (see comparison picture below). An earliest so far known lens has s/n #5102801 (private coll.). Lens opposite from Ilya Stolyar's coll.

PT2027. New generation of Jupiter-3 lens, released by KMZ since 1955. Probably recalculated optical scheme. New serial numbers system, starting from #000001. Very limited batch of these lenses released in 1955-1956.

PT2027 - Jupiter-3  #0000102.

 

  

PT2030. Lens almost identical to PT2025, but released by ZOMZ (Zagorsky Optiko-Mechanichesky Zavod) in 1956-1962. Slightly changed body design, old ZOMZ logotype on the face plate.
