Patent: Canon RF 11-24mm f/4L and Canon RF 8-24mm f/4L Fisheye | Canon Rumors

Yes, it is possible. But Canon did not design the RF lens in this patent that way. The back focus distance is 13.6 mm, so the rear element of the lens is already inside the camera body.

The RF 11-24/4 lens in this patent, assuming it has a built-in hood like the EF version, seems to be only <1 cm shorter than the EF version. It does appear the RF lens will have smaller diameter front element groups, and since that’s a big chunk of glass the RF version will likely be much lighter.

That also suggests some reliance on digital corrections as seen with the RF 14-35/4L.
