Well here’s a fun optical formula from Canon discovered by Canon News, a Canon RF 135mm f/1.4L USM.  The Canon EF 135mm f/2L USM is an all-time classic, and this would certainly be an amazing offering worth of the new lens mount.

I think there is a higher than normal probability that such a lens design will make it into a consumer product.
