After release of RF 50mm f/1.2L and RF 85mm f/1.2L USM lenses, Canon is planning to release more f/1.2L prime lenses in the near future. The next f/1.2L lens could be RF 35mm f/1.2L USM Lens, release date in 2020.
And the rumored RF 24mm f/1.2L USM lens may also coming, but not in the 2020 RF mount roadmap.
