    D500 Low-Battery Autofocus Issue

    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!

    Coincidentally, my D500 just went dead with an empty battery. I charged the battery for about a minute, put it back in and checked the menu: 1%. In spite of that, the camera auto-focused just fine. Seems your issue was something else.

    I'd be curious why the top LCD showed a charged battery, and the menu showed 5%... That should have shown a battery bar in the LCD with barely 1 bar

    Maybe it needs more juice when focusing a screw drive lens then an AF-S lens.

    Seems reasonable to me. The older screw drive may not be as efficient, electrically, as the in-lens servos.

    That would seem plausible, but every lens I tried on it was an AF-S lens...

    It was showing one bar, which should have lead me to change batteries. However, I was in a such a hurry with an unexpected task before I left, I only took a few minutes to put my bag together, and didn't check everything like I should have. I'd like to say that this will never happen again, but I don't want to lie about it. (I know that it will eventually happen to me again...)

    This is good to know, although not what I wanted to hear. I have never experienced this issue with any other camera that I own, so it very well may be another issue. The humidity last night was terribly high, which may have been a factor. I haven't charged the low battery yet, so now that the camera and lens have been in a moderate and dry environment for about 14 hours, I'll put the low battery back into the camera and see if it can be replicated. I'll also try the battery in my D750 to see if the issue is replicated with another camera. Depending upon what I see, I may be in contact with Nikon USA for service.

    Good way to shoot me down, but glad to have the truth out there.
