I think that one of the Pentax lenses that may supposedly have involved some Zeiss/Pentax collaboration is the the K 28/2, which uses a floating element. Actually, though, it is not clear in my mind, but wouldn't IF lenses be, in effect, lenses that have floating elements (inasmuch as one or more elements move relative to the other elements when focusing)? Or, to put it another way, couldn't the term be applied to any lens that moves elements (or groups of elements) differentially, compared to other elements (or groups)?
