Canon has said in various EOS R and RF mount presentations that the RF mount is going to allow them to make some “world’s first” type of lenses. We’ve already seen proof of this in the RF 28-70mm f/2L USM,
We’re told that an RF 14-21mm f/1.4L USM is currently in advanced development and will likely be one of a couple of world’s first lenses coming for the RF mount next year. After speaking with the source, we did confirm that there’s more to this than just a patent published here back in November.
The same source said that a “crazy” prime lens will be coming for the RF mount next year, but that the focal length and speed were unknown at this time.

My not be too bad. A 14mm f/2.8 aperture is 5mm wide; a 1.4 is 10mm wide. You can think of it as double (which it is) but it's also only another 5mm. For Americans' that's 0.2".
If it just was this simple with super wide angle lenses. The problem isn't directly the aperture size, it's that a single surface of glass can't bend the light enough (damn you, physics!), so you need to do it in multiple steps.

Problem is, those people only look at the mistakes.

It’s more about the perceived ”innovation gap” between Canon lens division and the camera body division. But it is definitely a deliberate strategy from Canon’s part, at least partially. One reason Sony has had to go all in with body features is that (besides being a market underdog) their lens selection was (and still is) not there.

The patent also lists a 12-20/2 lens of about the same size. While long at around 190 mm length is not to change during zooming. Key element of the patent is a resin lens element (element OE in the patent) which is placed in a sandwich between two glass elements at the image plane end of the lens. Element OE is described as being of low dispersion and extraordinary dispersion so it might not be the cheapest piece of plastic ever sold.
