I wasn't saying there was a crossover. If-and-when I go into R-land, it will be to fill a different niche. To be honest, I've yet to identify anything I *personally* would need an R or RP or R<fill in the letter> to do. Right now at my current ability, I can't justify an R (or RP) to myself. But I seem to be coming into this at just the right time--by the time I *am* able to justify full frame, I should be able to step directly into mirrorless. (And waiting means I will have more R-type body choices.)
Anyhow, the current models seem to have a wider Field Of View...and less total detail than the M6-II (which I will buy, if an M5 II doesn't come out first). I can get a better tradeoff than that just using a shorter lens (and cheaper too) on an M6 II. (Obviously, that's not all there is to it--the FF lens will of course be a better quality optic than an EF-M lens. But I can have that largely covered too, with the adapter and EF lenses. (It won't be one of the super RF lenses, but it will be a vastly better lens than an EF-M lens.)) Yeah, that's my gut telling me to wait and see, rather than just jump on an RP now, but that's what I think I should be doing anyway. Meanwhile, I did enjoy the R I "played" with a couple of weekends ago (they had no RPs), though my primary mission was to try out Fv mode (which I was delighted to see is on the M6 II).
