Okay, I am a convert. I am overly impressed with the little bit of performance that I have experienced with the Z8. I am only 150 pages into Steve's set up guide. Went on a walk with my dog and took some test shots. I used animal detection with the 3D and some of the other area modes. I put my dog in a stay and walked about 200 feet from him and got on the ground before calling him. Every image of him running toward me is in tack sharp focus. I don't even know what I am doing yet! Even more impressive is the low light performance. While going through the menus last night, I shot an image of my dog at 14,400 ISO. I cannot believe how clean it is compared to the D850's images at 6400 ISO. Now I wish I had that low light performance with the bear cubs in the Smokies last month. I am definitely pleased with the Z8.
