Canon News has uncovered a patent for a new super wide angle RF mount zoom and it looks extremely impressive.
US Patent Application 20180314060 shows an optical formula for an RF 14-21mm f/1.4L. That's correct… f/1.4!
Both Canon News and I had to read the patent multiple times to make sure we weren't reading it incorrectly. If Canon wants to do these “look what we can do lenses”, I have no issue just letting them do their thing.
This patent also mentions optical formulas for an RF 16-35mm f/2.8L and an RF 12-20mm f/2L
