Tomioka
Tomioka was founded in 1924 in Tokyo, Shinagawa by Tomioka Masashige (冨岡正重) as Tomioka Kōgaku Kenkyūsho (冨岡光学研究所, meaning Tomioka Optical Laboratory).[1] The first lenses were released around 1932.[2] They were the Lausar (ローザー) four-element Tessar-type lenses, available in 50mm, 75mm and 105mm focal lengths.[3]
The company name was changed to Tomioka Kōgaku Kikai Seizōsho (冨岡光学機械製造所) in 1933.[4] It was in Tokyo, Nihonbashi for some time and it was located in Tokyo, Ōmori in 1943.[5]
After the war, Tomioka Optical Company Ltd. supplied lenses to a number of Japanese camera makers like Yashica and Royal Camera Company. In addition to the Lausar, other types and brand names include Tominon, Tominor, Tri-Lausar, Tomi-Kogaku, Auto-Tominon, Tomi-Yashinon, Yashimar, Yashikor, Yashinon, Heliotar and Lumaxar. (Yashinon lenses have a reputation of good quality.)
Tomioka gained such a good name that this was the plant where Carl Zeiss licensed optics were made for Japanse cameras, like for Contax.
