Yesterday I posted a patent showing the optical formulas for both an RF 15-35mm f/4L and an RF 16-35mm f/4L. I noted that an RF 14-35mm f/4L is rumored to be coming in 2021, and I did wonder aloud if that was a type, but it appears Canon is definitely working on an RF 14-35mm f/4L optical formula.
It looks like this design of an RF 14-35mm f/4L has an internal zoom and will likely have IS as well.
