Canon EOS R10 - a pleasant surprise :)

It's the kind of camera that the M5 should have been. 80D sensor, great AF, no nonsense.

Now Canon is finally succeeding it's mirrorless 80D  it's a bit late to the party imo.  And if you like portraits (who doesn't?) the M50II has the huge advantage of being compatible to the ef-m sigma 56mm f/1.4.  And the RF 35mm f/1.8 will give you f/2.8 56mm equivalent, being just too tight for a general walk around lens, and it's equivalent max aperture isn't very exiting either, especially for the price. The RF 24mm f/1.8 is even more expensive. Last not but least the stm AF of these lenses will hold back the AF performance of the camera.  The fast focusing non L zooms aren't a great match to the typical high ISO performance of a crop camera when using shutter speeds typical for situations needing great AF. The L zooms are waaay too expensive for this budget camera. For wide angle you'll need to adapt old ef-s lenses.....  Finishing the mirrorless 80D for a new mount with only 2 crop lenses makes us wait even longer before we can shoot that mirrorless 80D with the glass it needs.

I still fail to see the headline of this camera. In combination with non L glass the AF advantage is gone.  If you're 80D + 18-135mm got broke and you don't shoot with other lenses and you're on a budget it makes sense to replace it with R10+18-150mm. If you want anything more than that I would go RP any day, as that one at least squeezes all the optical detail out of the non L RF lenses, while it sits around the same price.  A used R is even more bang for the buck, and not a whole lot more expensive these days.
