Canon News discovered a patent application that features a Canon RF 24-80mm f/4. It's almost a given that like the EF mount, Canon will come out with a f/4 set of zooms for the RF mount, especially since Nikon has already released an f/4 UWA and normal zoom.
Canon RF 24-80mm f/4 patent:
- Focal length: 24.72mm 48.09mm 82.45mm
- F number: 4.12 4.12 4.12
- Half angle of view: 41.19° 24.22° 14.70°
- Image height: 21.64 21.64 21.64
- Total lens length: 119.50mm 134.52mm 149.55mm
- BF: 13.50mm 18.71mm 22.73mm

why not? EF also has 24-70 and 24-105
However it also wouldn't surprise me if this was a 'mid range upgrade' kit lens.It would fit in well with the 70-240 f4 zoom patent that was release earlier, especially if they decide to do the 70-400 f4-5.6 zoom they patented as an upgraded alternative. I always had a hard time coming to terms that that there probably will not be an aps-c RF mount, that it would all be full frame. But as time goes on I am seeing that as more of a possibility., and patents that show they are moving the RF into lens ranges that were equivalent to old 35mm film based consumer focal lengths only strengthen that argument.
With 13 lens groups and 18 lenses I expect at least very very good IQ + it seems more refined than the RF 24-105 (whatever triggers that "emotion" in my brain, maybe it looks tidied up in terms of curvatures and diameters of the lenses and it has one group less so two surfaces are missing to diminish the contrast!).

If M series is going to be the crop series then Canon needs to step up development of lenses for it.
Of course the little Rebels could survive, be upgraded and keep the EF alive.
So many paths, wow.
I suspect we'll see a followup to the RP next year. It wouldn't surprise me if we see an entirely new sensor that slots somewhere around the 32 megapixel size for it, to more or less match the megapixels on the canon m mount.
I would much prefer having the 80mm end for a candid portraiture At the event.
Sure you can use the 70-200 but having the 80 mm end in the shorter zoom lens is fantastic from my perspective.
Do you mean an affordable 85mm prime? Otherwise there are already two RF 85mm 1.2L primes.
