Hi
Well, as an hobbyist, I change camera body every 10 years, coming from 7D Mki, the R8 will be my first Full Frame.
Why the R8 instead of the R6Mkii?, obviously the price, for 1.000$ less I can afford a great RF lens.
Why the R8 instead of the R or RP? For the autofocus of the R6Mkii, I do not care about a 2nd card slot, nor for IBIS, I like smaller battery, less power for sure but also less weight and a compact body.
