I bought my M50 knowing this will - according to Murphy's Law - force the introduction of a FF mirrorless.
But no frustration anywhere because I like the M50's IQ and ergonomics despite the fact that I like real controls. Canon made the interface as good as possible for such a small camera and exploits the potential of the touch screen interface to the max. After a one-week stay in a youth hostel I enjoyed the light weight, compact size and the - for a mirrorless - very good battery life (300 shots, some videos, some substantial image review and "menu work", two bars in the batt indicator were shown at the end).
Maybe the M50 will get a big companion in the near future and I will be happy to have a sub kilogram FF alternative with all the goodies of DP-AF, FF resolution and low light IQ, Canon ergonomics (I am trained with) ...
Lens selection: If the RF 24-105 has very good and consistent IQ (over zoom range / over image up to the corners, good flare resistance) it might be "my lens" for every day use and the RF 1.8 35 macro seems to be a good alternative to the 2.8 40 pancake coming in at similar weight and size (if adaptor is included) for low light/ultra compact/very good flare resistance if it is not a true 1:1 macro with lots of lens groups.
One question: Is the ring close to the filter mount really movable or is it just for look and feel to differentiate the RF lenses from EF lenses? Hopefully it can be used to set f-stop or Exp comp or color temperature or ... - just thinking about a stop-less f-stop setting for video!
And, Canon, please give us a "setting creator software" - these cameras have so many options composing them on a 30" computer display would simplify things dramatically and give us C1 ... C9 at least via the personal menus!
