Hi,
not getting into the "Made in XY means what?" discussion.
But for those who really think that Zeiss gave away trade secrets when giving Kamakura the specification for the Conquest coatings, I have to say that multilayer coatings are a 50 year old technology. And the number and tuning of layers for a specific transmission number and color rendition is NOT the hard part about it.
The real secret is to have a process to apply these layers in the required quality and with low reject rates. And I am quite sure that Kamakura (as well as a lot of other Japanese, Taiwanese and Chinese optics manufacturers) have had that long before Zeiss approached them about the Conquest and maybe gave them the specifications for their trademark blue/green color rendition.
