As quickly as I read this patent, I instantly considered somebody. The Canon Rumors group is aware of who I’m speaking about.

This patent covers the optical method for an EF 50mm f/1.4 with an apodization filter, maybe this may very well be a part of a brand new line of “DS” lenses, first began with the RF 85mm f/1.2L DS.

The aim of this patent is to enhance the bokeh of the lens utilizing new apodization know-how that Canon has developed.
