Patent: RF prime lenses including an RF 24mm f/1.4L USM and RF 50mm f/1.4 USM

Yes, but Leica M lenses are not that big. They are known for sharpness and aberration control. And I wouldn't say that their small lenses are not sharp across the field. And distortion? I know they have the rear element much closer to the sensor. But the RF is not that far away, as I remember.

I can confirm that my 50mm Summicron is not only small and lightweight, but also dead-sharp, corners included.
And I'm speaking of a 1969 (!) lens, Canon, do you listen?
The newer Apo Summicron 50 is certainly sharper than any other 50mm on the market.

we’re all still waiting for a new 50mm f/1.4 lens from Canon. I can already see the “Shut up and take my money” memes

Hmmm, this is a 13-element lens and if it owes anything to the double-Gaussian design I'm not seeing it.

Hopefully Canon will release a lot of new RF lenses in the coming year, because Sony is doing very good on this side. Their new 1,8/14 looks quite amazing and Canon don't have anything to compete in this range. Just like the 200-600 and some others...
