As soon as I read this patent, I immediately thought of someone. The Canon Rumors community knows who I’m talking about.

This patent covers the optical formula for an EF 50mm f/1.4 with an apodization filter, perhaps this could be part of a new line of “DS” lenses, first started with the RF 85mm f/1.2L DS.
