We've previously reported that Canon will be introducing an RF 500mm f/4L IS USM as their first super telephoto lens for the RF mount.
Now we're hearing that an RF 300mm f/2.8L IS USM will also be launching sometime in 2020, and the source has claimed that this lens will come with a “new and unique” feature for super telephoto lenses, unfortunately, no details about this were given.
I think we're going to see a lot more professional lens announcements in 2020 for the RF mount.
The source did clarify that new versions of the EF 300mm f/2.8L IS II and EF 500mm f/4L IS II aren't in the plans for Canon.
Switchable 1.4x & 2.0x teleconverter
Cheap?
300/2.8
420/4
600/5.6
And with excellent IQ. Maybe...
And I'd quite possibly buy it too...
or new and unique feature for super telephoto lenses - just that it would be the first one with RF mount :D
Canon's designers obviously feel that extendable lenses are fine for R mount L lenses like the new design on the 70-200 RF. Maybe a mechanism to extend and lock into place and collapse again when stowing away? There will be plenty of people who will whine about durability, but with a substantially different method of focusing using pdaf the mechanism being very slightly off over time might not make as much of a difference provided the camera can determine this and adjust.
It also might win converts to the system for the small and light argument (although i dunno how light it would be)
Speaking of retractable, I wonder why that monster hood which ends up reversed over the lens by fiddling with a knob couldn't just slide back into that location. Of course that still leaves the clumsy lens cover to deal with.

The 100-400 works well for Macro.

That’s a great idea, I just hope Canon has thought of it to.
