According to recently rumors on CR, a loose Canon RF mount lens roadmap for 2020 has been shown to select photographers, and the plan is to release between 6 to 8 new RF mount lenses in 2020.
According to rumors, these rumored lenses are mostly the f/4 zoom lenses, since Canon has already announced f/2.8 zoom lenses, it is time for Canon to release some cheap and light f/4 zoom lenses. Canon will also release at least one “crazy look-what-we-can-do” lens in 2020. And there will also at least one fast L prime lens and some non-L lenses in 2020.
