Pentax and Zeiss licensed the technology from OCL and Pentax beat Zeiss to market by a couple of months with the first multi-coated consumer camera lenses in 1971. Multicoating was used earlier for technical applications, but with methods that weren't practical / economical for consumer lenses. I don't have time for chapter and verse on this; I'll just say that I've been wrong before and I'll be wrong again, and if you want to cite your sources I'm willing to listen. Better yet, write an article on it for me, and educate me and all my readers! - --Mike (whose dad happened to be Director for Space Applications at NASA during the Ford administration)
