With last night's announcement of the new Nikon D850, the only thing that we possibly know about it is that the camera will apparently have an 8k timelapse mode. But if history is going to repeat itself, we may see something that Nikon has done before--use Sony's Sensors.
The Nikon D850 is said to be a high resolution, high performance DSLR. And when I see that, I think about the Sony a99 II in some ways. Considering that Nikon has been using Sony sensors for a while now for many of their cameras, it would make sense that that's what we're going to see. . thephoblographer.com
