This is a rather interesting Canon patent application, and it might well go into production…
I think it’s just logic to expect that Canon will continuously release RF mount versions of most of the lenses currently existing for the EF mount. RF mount macro lenses for sure too.
Two Canon patent applications in Japan (2020-60660A and 2020-60661A, spotted by Hi Lows Note), show that Canon R&D departments are working on such lenses, and we think here too we have a patent application that might hit the market sooner or later. Optical formulas for RF mount macro lenses with focal lengths of 90mm, 100mm and 180mm, all f/2.8, are discussed in the patent applications.
More Canon patent applications are listed here. Some particularly interesting patent applications we think might get into production are these:
