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.

If the specs are a RF 14-21mm f1.4 L , it's going to be seriously expensive!
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.

Some feelings can only be expressed by emojis. :)

Size, weight, cost...sure, I'll want to see each of those, but this will be a lens I will be very happy exists in the Canon portfolio....and it may be even end up in my bag.

It's like Canon is the girl you want to date and Nikon is the girl you want to marry...

I love all the insane lenses, Canon, don't get me wrong. But what I REALLY need for my R is some 35/2 or 50/1.4 or 1.8 optimized for portability. I don't need it to be an actual pancake lens, but I'd like it to be smaller than an EF pancake on an EF-to-R adapter (which I recently tried) as well as have an extra stop or two. I don't care if it's not mega-sharp and I could even lose the control ring.

Until then, to keep my camera in my backpack at all times I'm having to resort to extreme measures...

AFAIK, there aren't any primes that fast for any FF camera, which would make such a zoom really amazing.

People would still complain Canon isn't innovative, though.
Problem is, those people only look at the mistakes.

OK, here's the patent: http://pdfaiw.uspto.gov/.aiw?PageNum=0&docid=20180314060

It looks like the front element is 86.215mm across.

The current 16-35/2.8 III is 88.5mm outside diameter, while the current 11-28/4 is 108mm wide.

It's possible this lens wouldn't be more significantly bigger than that.

Well I’m already saving for the 15-35, so I’ll just keep saving because I’d rather have this.

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.
