Just got my A7r II and it is a pretty awesome camera. I don't feel like the dynamic range is that different from my D800, the detail is better though. The 5-axis stabilization is awesome, it really helps in low light. I feel like I get a lot of latitude from the files. The autofocus seems about on par with the NX1 I was shooting with and seems to do a good job in most situations. I don't know if it is on par with my D800 without doing a side by side comparison. I am fully converted to having an EVF instead of an optical viewfinder for most things.

Here are a few sample images:
