Patent: Some loopy quick RF mount prime lenses, together with an RF 18mm f/1.0L

Again in August, I discussed that Canon was engaged on an entire line of f/1.2L prime lenses for the RF mount. To this point we’ve the RF 50mm f/1.2L USM and the RF 85 f/1.2L USM, however there are extra clues that extra f/1.2L lenses are within the pipeline.
