A patent application for some wide-angle fast prime optical designs has been uncovered by Canon News.
Included in this patent are optical formulas for an RF 22mm f/1.4L USM, RF 24mm f/1.4L USM, and an RF 35mm f/1.4L USM, We have seen multiple patents for both the RF 24 f/1.4L and RF 35 f/1.4L, but keep in mind that we have also seen patents for an RF 35mm f/1.2L USM, which appears on our Canon RF lens roadmap.
I feel like I'm beating a dead horse, as lots of lens announcements have been delayed for obvious reasons. I have no timeline for any of the lenses on the roadmap, but I do expect Canon to have a lot of lens announcements in 2022. Canon is also probably making the right call on delaying announcements that they cannot manufacture to the levels of demand.
Of all of these optical designs, I do believe that the RF 24mm f/1.4L USM is the most likely lens to hit the market in the future.
There have also been patents for an RF 28 f/1.4L USM, which is what I want in case you haven't been paying attention to my incessant whining for one.
