Sony Alpha A7R II

Best camera I own for the time being.
With a 42M IBIS* sensor, 5 frames/sec, over 400 focusing points, ISO invariance*, you can't possibly get wrong with a shot (you are out of luck if you did).
As my Canon glasses (so sad not for those super telephoto lenses) can be used via my Metabones IV adapter, I use it almost everyday.
I have heard that purple frindge would occur when you shoot with a strong backlight, but I didn't have such an issue up till now.
The only problem is, the file size are too big that I have to resize them to save my harddisk space.
I probably need to upgrade my PC(an i-5 machine) at the moment to process my images faster, which is something to consider before buying this beast.

* Google "ISO invariance" and "IBIS sensor" for details.
