Canon should really focus on improving their sensors and affordability instead of bigger resolutions.
They are far behind at the point dynamic range, just look at the recent DSLR which are still 3 stops behind on the new sony mirrorless.
Just look at Arri Alexa. THE go-to camera for professional productions. But still isn't able to shoot 4k just yet.
RED does the same as Canon, only focus on resolution. News flash; it's useless.
Maybe 5% of the people have a monitor or TV that can support 4k at the moment. Also youtube is fake with it's 4k as it is so compressed you can hardly tell the difference between 4k en 1080p.
And if 4k is useless, than what does that make 8k?
"Fastest autofocus of all professional camera's"
So basicly DSLRs aren't professional camera's anymore? Because the last time I checked, mirrorless camera's were waaay slower with autofocus than DSLRs.
I have experienced this myself, going from DSLRs to mirrorless and being both a DP and photographer.
