it's a shame that like many patents, CW gets it entirely wrong, even though all he does usually is read what I wrote. I've even tried to help and correct him on some of his off base conclusions or comments on patents, only to get into a brick wall against head session after back and forth emails.
here's the original post that CW "copied" and somehow even in that translation, got it wrong:
This is a strange lens patent application from Canon. Atypically there are 5 or so different sensor sizes that Canon create lenses for. broadcast cameras, 2/3" compact, 1" powershot, APS-C and full frame. Every now and then, you see strange ones, such as this one, where the image height is...

I mean I even explain why it can' t be APS-C :/
That 12-48mm was for m43 sensors, and not for the EF-M unless they magically shrink the size of APS-C sensors when I wasn't looking.
the 55-250 2.8-4 would be quite large. I doubt you'd see that any time soon (consider the size of a 70-200 f/4)
