I saw this too and my suspicions are that Canon is really falling behind in the sensor technology. With the two year old sensor in the new EOS R and the so so sensor on the 6d mark ii, I think with in the next two years we will see how far behind they really are. I know there is a lot more than the sensor for a great camera experience, but technology moves fast and once you are behind it is really hard to catch up. I know people think Canon is just holding back and maybe they are on a few things but sensor wise I think they are just not capable yet of doing what other camera companies are. This doesn't mean you can't take great picture. I still only use my original 7d and the 5d mark ii. My 5D mk ii at iso 100 properly exposed shoots just as nice of picture as the 5d mark iv, but with Canon only releasing new camera versions every 4 to 5 years I hate to think what Sony will have by the time the Canon mk v comes out. Who knows thought Maybe the 5dsr ii will be the one that really shines. Lets hope, because if I wanted what the EOS R has I would buy a sony a7rii with pretty much the same specifications but a better sensor.
