We’re told that a loose roadmap for RF mount lenses in 2020 has been shown to select people and that the plan today is to release between 6 to 8 new RF mount lenses in 2020.
Amongst those lenses will be f/4L zoom lenses, perhaps some of the recent patents give us some clues.
At least one “crazy look-what-we-can-do” lens is coming next year.
There will also be at least one fast L prime lens and a couple of non-L lenses, it’s unknown if they’ll be zoom or primes or both at this time.
There has been no world on tilt-shift or macro lenses for the RF mount as of yet.
