My brand new D850 I bought in end of december 2017 had a lot of problems revealed during the course of the subsequent weeks. The problems were as listed below:
1. Control panel still lighted (ON) after turning off the camera
2. Menu settings not being saved (for expl I wanted to change the prefix of file name. After saving the new one and exiting the menu, when I come back it still shows the old prefix.
3. Battery drain is important. Even if the camera is off, and the airplane mode is ON, overnight the baterry is completely empty.
4. After shooting picture, the monitor on the back is not displaying the picture I took, but an old one shot a few days before.
5. When in shutter priority mode, with the correct knob, I cant choose a speed higher than 1/250.
6. and many other problems I cant list here.
Has someone came up with the same situation? If yes did you get a speedy repair from Nikon ? What did they say culd be the source of the problems ?
