Essentially the R8 has the performance of the R6ii in a smaller, lighter body at $1000 less money. There are trade-offs in ergonomics, weather sealing & no full mechanical shutter, but for someone like me, coming from an RP, it's a very tempting upgrade. I tried an R6ii recently, it's a fantastic camera, but I've got used to the smaller, lighter RP and found myself wishing it was smaller. I will defenitly try an R8 when the opportunity arises. One of those 2 cameras (or a discounted R6) will likely be the eventual replacement for my RP.
