  The optical design in this patent includes:

  Canon RF 50mm f / 1.8

  Canon RF 80mm f/1.4

  Canon RF 85mm f/1.4

  Canon RF 85mm f/1.8

  Canon RF 100mm f / 2

  Canon RF 135mm f / 2

  This obviously won’t all become Consumer products, but CR believes that this shows that Canon is developing a longer aperture lens for the RF mount.
