I believe Rollie uses slightly different Multicoating technologies >on its Zeiss lenses ( compared to Hassleblad ), so perhaps leica does the same. Both Leica's multi-coating and Rollei's HFT are identical in process to Zeiss's T* and both are licensed to use this process by Zeiss. The precise mix of chemicals used in the coatings may vary marginally from manufacturer to manufacturer, but not significantly. The corporate wranglings that led to Zeiss and Pentax pooling research to jointly develop the T*/SMC process and which later led Zeiss to license this to Rollei and then Leitz are a bit complex and a lot of it deals <<sniff>> with the demise of Zeiss Ikon.
