The long-rumored
RF 200-500mm f/4L IS USM has been tipped to be announced in November by various people.
The Canon
RF 70-200mm f/2.8L IS USM Z is also slated to be announced in November with a quick shipping time ahead of the EOS R1.
As for the
RF 24mm f/1.4L VCM and
RF 50mm f/1.4L VCM (again, I hate being patient), they're still tipped to be announced later this month, but we haven't heard anything recently about those lenses.
