WIPA was perhaps the acronym of a Japanese lens maker. The name WIPA NIPPON and a WIPA logo appear on
- Yamat-Anastigmat 18cm f/4.5 barrel lens for large format cameras (engraved YAMAT–Anastigmat 1:4.5 F=18cm WIPA NIPPON [unreadable]).
- Yamat-Anastigmat 21cm f/4.5 barrel lens for large format cameras (engraved YAMAT–Anastigmat 1:4.5 F=21cm WIPA NIPPON N°13xxx).
The name "Yamat" is certainly a peculiar romanization of Yamato (やまと or 大和), one of the numerous words meaning "Japan", perhaps playing with the "mat" termination of "Anastigmat".
- A triplet lens with the letters WIPA in the central element.
- Seen in a Japanese on-line auction as a single lens (February 2012)
