for a summary of the collaboration between Pentax and Zeiss by someone paraphrasing a book by an Asahi historian. It provides some details about how the coatings and two or three lenses began as joint developments but went their separate ways The writer summarizes the optical differences between the two companies' 15/3.5 and 28/2 lenses. No word about OCLI here; Pentax and Zeiss are credited with developing the SMC and T* multicoatings.
