Yet another silly question from a hobbbyist

So I've spent quite a bit of time researching camera bodies recently (I've been shooting with a Rebel t5i since 2013 or so and most investments in this hobby have gone toward lenses). Most of my time spent by no surprise has been toward the legitimacy of Canon's Mirrorless cameras. Specifically the EOS R and EOS RP have caught my eye and taken up a bit of my time. One of the many things that tempts me on this investment is the viewfinder in mirrorless vs dslr as due to my casual/hobby nature in photography being able to see real time the look of the photo in the viewfinder would be awesome. Anyways, onto the questions.To me the only real differences between the EOS R and RP (For about 800 bucks difference) were around 4 MP, 3 frames per second continuous and the resolution of the screen. Am I missing something here or is the 800 bucks difference really for that?As far as hopping on the mirrorless bandwagon goes, are there any risks that I might be missing here? From what I understand there are simple well working adapters for these mirrorless bodies for any lenses that I would already have. Is doing that going to cut out on some of the benefits of the new body (i.e. better autofocus)?Is it still early enough in this process that it seems like coming generations of the mirrorless cameras more than likely are going to have better value?Those are my main questions right now and look forward to any of your responses and any extra insight you all might have. via /r/photography https://ift.tt/2Rl5Tcd
