The patent includes this drawing of one way in which these lens designs could be employed…Personally I'm more curious about a patent application mentioning (APS-C?) designs for 10-21mm f/2-2.8 and 11-28mm f/2-2.8 wideangle zooms, though I'm not sure they are meant for consumer RF mount cameras (Richard?):

If it is an APS-C design, the 10-21mm would be an interesting option for me (the other wouldn't be wide enough to replace my current EF-S wideangle zoom).
