Yes there have been some Leica R lenses that have been modified or adapted to fit the Leica S cameras including the Leica R 400mm f2.8 Modular Apo Telyt lens. As to what they show on the website, I am not sure if that is the original lens that was reported. But if it is, the lens itself had to be cut and modified if I recall correctly to work on the Leica S. Also, if I recall, the lens could no longer be used on a Leica R camera. Additionally, at this point, this only applies to Leica S cameras for Leica users that wished to use R lenses on the camera. In addition, in the film days we knew that some of the Leica R lenses including the 560mm f6.8 Telyt lenses covered even 6 X 7 format and some of these lenses had their tubes modified so that they could work on the Pentax 6 X & film cameras.
