The RF APS-C camera is a niche product for a small number of people prepared to pay a premium for an APS-C camera to use high quality lenses. Despite what these people think they are in the small minority of Canon's current APS-C
I also agree here. I’m the owner of a 7DMarkii, a 5DMarkIV, and an M50. All have different purposes.
I basically only use the M50 with the 32mm 1.4 or the 22mm f2.0. This is for when I want a super lightweight tag-along camera for the unexpected photo op, or just common family events. I would never hang a huge zoom on it because the ergonomics suck in that configuration. I would love the opportunity to replace it with an M5 mkii, and will be a customer if Canon ever releases one. Sorry—just can’t get behind the clunkiness of the detachable M6 viewfinder.
The R5 is a compelling option for me to replace both my 5DIV AND my 7Dii, because the R5 is now faster, has incredible autofocus, and
almost has the same pixel density of the 7DMarkii. Equivalent crop section of R5 is 17.58Mpix. Think that’s a coincidence that they made it
just under the 20.1 mpix of the 7Dii? Like, they couldn’t push the R5 to 50Mpix, so it would have same density. Also
just under the pixel count of the 5DSR as well.
I think there is a market for the R7, but it would need to have at least the 32Mpix sensor to be a huge step up in pixel density for birders. And it needs the ergonomics to handle big whites. And hell, maybe they will make some RF-S lenses at some point to sell more options to those that go down that path.
But I think the market will still exist for all 3 segments.
