This camera has posed some mixed feelings for me for sure, I do wonder if instead of saving the grand if I would have done better by getting the 5dmkiv. It's been stirring in my mind since before I got the camera. I figured the R was the future, had some good things going for it but kinda runs me in circles.
One has to do with processing the raw files, yes there is DPP and Photoshop and Lightroom but my classic LR6 will not open the files and no updates to it. More Adobe vaporware I suppose. But I knew this for the most part. I suspected DPP was going to have to get me by and my outdated LR6 was probably not going to work or be updated to support newer cameras (I think it'd support the 5d though I'm not sure) why? Because Adobe wants more money (I'd rather pay the 800 bucks every few years then this dumb subscription garbage... But that's another rant.
I have also been trying to get away from Windows (I have no interest in Mac) so of course been trying Linux, namely dark table and raw therapee and I guess Canon has opted not to release things needed for cr3 decoding to these devs. Proprietary software, right? :Rolleyes:
I thought with the camera being released a little while ago, perhaps with a rolling distro raw support would have found its way to Linux. Guess not. Sounds like it's not going to be for a while. I think even the m50 with it's cr3 files are not supported in Linux. 
Ok ok, really I do understand. These things where on my mind when I picked up the camera.
Using the aforementioned apps with my other cameras was a bit of a learning curve and challenge as it was in Linux.
Sticking issues number 2 pertains to the RF mount. No doubt this mount has some potential and a couple RF lenses I do find interesting like the 15-35 and 24-70 f/2.8 is (for both if I read things right) but I'm guessing a fairly high price tag (probably explains the slightly lower entry point of the R bodies) and neither can be used on my other 2 bodies (5dmkii and 80d) 3 if I count my elan 7 film body I've been experimenting with lately, that is really irksome.
Once again. I knew this fact: ef glass = does my bodies good, RF glass? Does one body good.
It has also been a bit awkward to use, but more use will probably get me used to it more.
These have been my main issues with this body. I knew this, I researched it but I wonder if I made the wrong choice and shoulda went 5d.
Don't get me wrong I'm not bashing the camera, I made the choice to buy it... The shutter is a nice touch, the potential for decent video should I'm interested in (haven't tried it yet, is the video quality still soft like in the reviews at launch?) No micro adjustment needed, live exposure, dpaf in video mode, nice images off the sensor.
I don't know, maybe I jumped the gun on mirror less 
Not really ranting, just giving my honest thoughts about this purchase. Anyone else feel similar?
