Big white lenses for the RF mount are a logical next step for Canon, and I was expecting to see at least a couple of them announced ahead of the Tokyo games this year, but that appears to still be in a certain level of flux, so who knows at this point?

Outside of an RF 300mm f/2.8L IS USM, all of the optical formulas that appear in this USPTO patent uncovered by Northlight Images are also part of the rumoured RF lens roadmap that I published a while ago.

Another of the rumoured lenses on our roadmap is an RF 1200mm f/8L IS USM, but I haven't seen any sort of patent reference for such an optical formula yet.
