Canon Patent Application: Canon RF 85mm F1.8 and RF 100mm F2.0

Two lenses I know are wanted in the ecosystem even though I know it looks like we got a Canon RF 85mm F2.0. There's still the likelihood we get the F1.8's and a most certainly a RF 135mm of some sort as well.

These lenses look to be quite the sophisticated optical design, more than you'd expect out of cheaper consumer lenses.
