Mostly love!
I bought it for my nieces wedding in August, which was an early evening event. I was worried my D810 and Fuji X-T3 wouldn't pull it off. I was relying on subject and face detection and it did a great job, with one exception. My AF sensor randomly ends up in the same spot in the upper left corner of the screen. I can be using the camera, and pull it away from my face and then when I look through the viewfinder again, it's up in the corner. I'm not touching anything and my screen is not touch enabled. So I figured it for a bug that would be worked out in a firmware update. When Nikon released the update last week, I was disappointed to see it wasn't mentioned. I ran this past service shortly after buying the camera, but they didn't have an answer. This issue caused several out of focus shots because I was reacting quickly to the situations before I realized it and found it hiding up in the corner. Aggravating for sure, but other than that, it's a really nice camera with the most confident AF system I've had yet.
