I have been reading about the mirrorless cameras and also always have my smart phone with me so I often use it to snap a snapshot (the camera you have...)
But I just bought a Canon 6D Mark II. I am not against the EOS R it is just that I wanted to cameras that have virtually the same controls so in a pinch or a rush I don't have to think but can operate on istinct. If the EOS R or a similar camera had the same control layout as my 80D I might have gotten that. I did try the 5D Mark II but after a week of using both I was still having to think about what I wanted to do with the different controls. If I were to dump the 80D and buy two new cameras or an older Mark II and a new Mark IV that would have worked but out of my budget for now.
Of course now that I have been using the full-frame 6Dii dumping the 80D and 6D and getting two 5D's would be tempting. I will live with what I have for the next few years...
it will probably be a 2-5 years before the EOS R mark II is out and I will see how that is. The only thing at this time that intrigues me is the totally silent shooting, it is rare that I want to do that but I can see the advantages it in many instances.
