T.Y.O.W.

The acronym T.Y.O.W. corresponds to a Japanese lens maker based in Tokyo, whose full name is currently unknown. It made Taiyo-Anastigmat barrel lenses for large format cameras. These are usually marked T.Y.O.W. TOKYO TAIYO–Anastigmat. The lens name certainly comes from the word taiyō (太陽), which means "sun" in Japanese.
List of known Taiyo-Anastigmat lenses:
- 18cm f/4.5 (reported only)
- 21cm f/4.5
- 21cm f/6.3
- 210/6.8 (reported only)
The Taiyo lenses were already existing in 1941.[1]
Notes
- ↑ An advertisement by Kuwata in Asahi Camera April 1941 mentions the Taiyo as one of the lenses onto which one could attach the Bimagon wide-angle attachment.
