To the OP, I think it is too early to tell. This is one where I would say wait a bit to see what actual reviews have to say (tho my sense is that all reviews of Canons trash them even though they are excellent cameras). I will say though the eos rp interests me more than the R because of its price and small size. This is just a personal thing though. I mostly use a 5d mk iv but I have an sl2 that I use in my kayak and other boats. I actually really like that camera for all kinds of perverse reasons (it has almost no fancy features so it is like me and the camera or something like that) and it works for me. The eos rp strikes me as a camera of about the same size that actually has some features I might use and is small enough to be a travel/hiking camera. I have been using a Sony a7riii for that purpose, but I miss shots because odd features I don't know existed get activated and I have to spend way too much time figuring out what I did wrong and then figure out how to fix it by which time...... I like the announced simplicity of this one. My general sense is that it takes awhile to get the bugs out and what I really want is some kind of 5d camera that combines the features of the 5d mk iv with the megapixels and resolution of the 5dsr, but Canon seems to be going more in a consumer direction now, so who knows when or if they will produce such a camera. In the meantime, if I were going to move to Canon mirrorless, I think the rp makes more sense. I am not sure I see the point of getting the 6dII at this point, but that is just me.

Cameras are really about what YOU shoot and what YOU like and dislike in a camera's features, so my opinion here isn't particularly relevant, but I have used a lot of cameras from different companies and the rp has peaked my interest more than some others because of investment in glass. Otherwise I might seriously look at one of the Nikon zs.

Selene … there IS a 5D S R Update in the works … never fear!!!!! …

Both of these cameras (6D2, RP) appeal to me, because of their low cost, compared to ALL other FF Canons. In fact, the only Spec I can see on the 6D2 which bothers me, is the lack of 100% VF coverage. Other than that - it comes across, to me, anyway - as a pretty good bundle, with its built-in GPS, and fully articulating touch-screen. (Only wish it were 3.2" instead of just 3") ... there are some reservations, however, about how well it performs in Low Light, as well, as how good the Res is, in low light. Some reviews have indicated, the Res falls off, in the areas, in which the AE has not done its job, effectively. It remains to be seen whether these same problems, plague the new R and RP MILCs. We'll see ...
