Hi Peter: According "The Evolution of the Japanese camera", Condax and others NY 1984, Yashicamats never used a German lens, the Lumaxar used for the Yashicamat was made by Tomioka; Tomioka was the exclusive lens supplier for Yashica from late 1949, becoming a Yashica affiliate/subsidiary in 1968, and named the Tomioka Optical Corporation from 1969. Tomioka was lens provider for other cameras manufacturers too; after the war Tomioka developed a triplet called "Tri-Lausar" for the mass market. Tomioka became the Kyocera Optics division on 1983 and it was in the Tomioka plant where Carl Zeiss lenses were manufactured for Japanese cameras. The Lumaxar is a Tessar copy and it became "Yashinon" when Japan was allowed to export cameras to countries where there were registered names very similar regarding the name "Lumaxar", it seems one of the countries with this name issue was UK. Tomioka manufactured Japanese lenses from 1933 despite it was cheaper to import German lenses, but situation changed after the war.- All the best Carlos --- "Peter K." <peterk727@xxxxxxxxx> escribió: > Came across something interesting.
