Northlight has uncovered a USPTO patent that showcases various optical formulas for apodization lenses. It appears one of the embodiments fits the recently announced Canon RF 85mm f/1.2L DS USM.
Other embodiments in this patent include:
Canon RF 35mm f/1.4
Canon RF 28mm f/2.8
We don’t doubt that an L 35mm lens is coming sooner or later for the RF mount.
