Got mine in central europe one week ago.
The fast video autofocus and autofocus touchscreen are great.
4K video in 24/25fps is possible even with fast CF cards, instead of the super expensive CFast cards.
The camera doesn't work too well with most Tamron lenses.
For the price, it is very annoying that Canon didn't implement an internal timelapse function and also not the HDR photo mode from the last 5D models.
The most disturbing thing is the lack of focus peaking, which would have been very useful for manual lens photography and not only for video. PLEASE CANON DO ADD THIS AS AN UPDATE!!!!!!!!!!!
Sony doesn't protect their video department like Canon does, which is VERY refreshing and using the EVF of the A7R2 is way more fun than working with the 1DX2 unfortunately. After working with mirrorless going back to a DSLR is like being set back to stone age in some ways.
At Photokina in september Sony will release the A9, which addresses the few missing DSLR features of the A7 series. If it has 4K 60fps video and at least 6fps photo plus acceptable processing power, I don't see myself using the 1DX2 anymore already in half a year from now on.
So Canon has to hurry up and deliver mirrorless equivalents of their top DSLR models! Or AT LEAST implement the goodies of other manufacturers like focus peaking!
