My first post!
Is there any reason not to believe that all the M lenses will eventually be released as an RF version? I was at B&H last weekend checking out the R50 and the RF-S 18-150. It's a nice little package and the R50 has significant capabilities beyond the M50ii. It's compelling.
I have the M6ii and absolutely love it. It's a different beast than the M50ii. It has great compact ergonomics, a terrific sensor, and full controls. Nothing in the RF-S line offers that unique and desirable combination. So it's very much a personal decision and different for first time entrants into the Canon APSC eco-system versus existing users.
One more general comment. There is no shortage of cameras out there. All of them are more than capable of taking breathtaking photographs in the hands of a photographer with vision. For example, today I was in my office comparing my M6ii and 32mm f/1.4 lens with my Olympus E-M1mkiii with the 12-40 f/2.8. You know what? The pictures were indistinguishable on my 49" widescreen monitor. Sure, this was not a thorough scientific comparison, but I was kind of surprised how close the few pictures I shot actually were. So what I'm trying to point out here is that each person eventually finds the tool that they like the most. In my case, I had played around with the M6ii a few times at B&H and thought it was pretty sweet. It called to me and one day I eventually capitulated and walked out the door with it. Little did I know how fond of it I would become.
