I got out with both my D500 and D750 this evening and it was miserable, weather wise. 90+ degrees Fahrenheit and about 80-90 per-cent humidity. Out of the bag, both camera-lens combinations were fogged over, and I waited about 15 minutes to use the cameras. The D750 worked with no problem, but the D500 wouldn't automatically focus. So, I checked everything I could think of, and even tried all of the back-button focus possibilities, but the only way to focus was manually.
After returning home, I got the camera out and cleaned the contacts between the camera and lens, and even reset the back-button focus settings on the camera, but nothing worked. Then I happened to look at the battery level at the menu level, not just the top LCD. While the top LCD showed a charge, the menu battery check showed 5%. So, a new battery went in, and viola!, the auto-focus worked.
Lesson learned, again; always check battery power levels before you go out with your camera!
