Canon Patent Application: A Canon RF superzoom
This is a curious lens patent, while it certainly appears to be an RF lens, it's an RF lens that requires in-camera RAW manipulation at the wide end because the image circle is not big enough. It could also be these are for more consumer CINI lenses where super-35 is "big enough", as the patent application also indicates an image that appears like a video camera. However, 21.61 is much larger than the aytpical CINI lens as well.
Here are the embodiments;
