Zion and Optor
This article is a stub. You can help Camera-wiki.org by expanding it.
The Zion and Optor were made by Asahi Kōgaku and supplied to Rokuoh-sha, manufacturing branch of Konishiroku. This page of the R. Konishi website says that they were designed by Mōri Hiroo (毛利広雄) of Rokuoh-sha, the designer of the first Hexar lens.[1]
Notes
- ↑ Shashin to tomo ni hyaku-nen, pp.403–4, only lists the Zion and Optor lens names and says that some lenses were outsourced to Asahi Kōgaku, but does not explicitly say that these were designed at Rokuoh-sha. Lewis, p.182, only mentions the Optor lens as made by Asahi.
