Canon Patent Application: Canon RF lenses
In this patent application, we see what appears to be the Canon RF 35mm 1.8 Macro, however we see other embodiments that are certainly interesting from the Canon RF point of view, including a 16-35mm F4.0. The back focus distance is a bit deep for the 16-35, so we are a little doubtful that this would actually be the actual lens when it is created.
