But remember that you can't mount a RF lens on a conventional camera, and all RF cameras have all the magic corrections. That means you can make a 14mm that gives undistorted results for far less than before. If Nikon can sell the outstanding Z14-30 f4 for $1096, a sharp 14mm prime should be doable for $999. I'm just thrilled to have gotten the 11-24 used for a good price.
Magic corrections?
AFAIK, the only difference between EF & RF lenses, in this regard, is RF cameras can display corrected images in EVF, which EF cameras can't do with OVF. Otherwise, EF cameras apply in-camera lens correction as well, so JPEGs come out corrected as well.
If you're processing raw images, it boils down to Canon's lens design choices. OK, I would admit its magical that the EF 16-35mm f/2.8L mkIII's corners having only 5 stops of vignetting, proving one never needs to lift an image 6 stops, but that's a different story.
