First off, I use a 5D MklV and am very happy with it, no complaints at all. But were I coming to full frame photography for the first time with probably no L series glass I would have a very difficult choice between the 6D mkll and Nikon's D750, and I'm being generous there.
The 6D mkll and D750 I would imagine are often the gateway to full frame photography (in my opinion at least), from there follows a lot of money spent on L series glass, then a possible upgrade to the 5D series. Point is, whichever camera one chooses from these two will lead to a nice income stream for that manufacturer.
Canon aren't unique in having their latest camera 'slagged off' either. Nikon's D7500 is getting a much bigger panning than this.....as did the 5D MklV if I remember right. You can almost predict what result Nikon's D850 will get later this year. I hope to ...... the 7D mklll doesn't, that is currently in my sights.
I genuinely hope the data we are all poring over is supplanted by weekend and there are lots of relieved and smiley faces on Monday. Surely you try to compete with potentially your biggest competitor, the D750......don't you?
