ISCOMORPHOT 8/1,5x questions

Another webpage that claims that the camera's lens has to be set to infinity when using the Iscomorphot:

IMHO this isn't true. However if it is true, when your filter is most likely a lens that's used to force the camera's fix-focus-lens to focus to infinity. (Fix-focus-lenses for small-format-cameras are normally set to something like 3-6m (10-20ft) and not to infinity.)
However this can't be true as the patent for Iscorama (with the camera's lens set to infinity) is from 1967 (see http://www.google.com/patents/US3517984 ), while the Iscomorphot 8/1.5x already got advertised in some German magazines in 1959.
