T.Y.O.W.
Revision as of 06:54, 9 November 2016 by Heritagefutures (talk | contribs)
The acronym T.Y.O.W. corresponds to a Japanese lens maker based in Tokyo, whose full name is currently unknown.[1] It made Taiyo-Anastigmat barrel lenses for large format cameras. These are usually marked T.Y.O.W. TOKYO TAIYO–Anastigmat.[2] The brand name certainly comes from the word taiyō (太陽), which means "sun" in Japanese.[3]
The Taiyo lenses were already existing in 1941.[4] They were made by a relative of Mr. Yamasaki, founder of Yamasaki Kōgaku Kenkyūsho and maker of the Congo lenses.[5]
List of known Taiyo-Anastigmat lenses (with varying inscriptions on the lens bezel [see footnotes]):
- 18cm f/4.5[6]
- 21cm f/4.5[7]
- 21cm f/6.3[8]
- 21cm f/6.8 (reported only)[9]
- 25cm f/4.5[10]
