    Sorry, doesn't make sense to me. Whiskeyman had 5%, I had 1%. Ok, those are approximations anyway, so let's assume I had 1% and he had 2%. The 7100 is spec'd at 950 shots per battery load. Even if we discard that number somewhat and say you only get 500-600, as some users do, that still means he should have had 10+ average shots left when he experienced the issue. And we're just looking at the focusing system here, not everything else, while shutter, image storage, and (most relevant) image display together eat up much more juice than the AF system does. Just doesn't add up.

    Not sure where exactly to point, but my guess would be internal moisture, either in the lens or the camera. The D7100 is not particularly well-sealed. Anyway, glad the issue fixed itself. Personally, I would not lose sleep over it unless it becomes repetitive.

    Or..Perhaps his cam is not displaying the battery level correctly. I will not rest until this mystery is solved. To the Mystery machine!!

    Re: D500 Low-Battery Autofocus Issue

    Might be a continuation of the D500 battery compatibility issue. If you will recall the D500 has some issues in this area as it is not even compatible with some Nikon batteries, let alone third party battieris.

    What Nikon battery is it not compatible with? Mine has worked with every battery I've fed it, even the recalled ones. The recalled batteries don't provide the same number of shots per charge as the new models, but otherwise work fine.

    Re: D500 Low-Battery Autofocus Issue

    I think, under the circumstances you're fine... but, since everyone here seems to contend that a low battery doesn't effect the auto-focus... I'd be tempted to run a battery down as much as possible and test to see if in fact, the low battery was the problem or not...

    Re: D500 Low-Battery Autofocus Issue

    I was going to past a query here and on the Tam 150-600 thread about exactly this tonight. After repeated lockups and errors while shooting burst shots, I called both Nikon and Tamron support. Nikon was useless, as it was a third party lens and I could not reproduce it with my 50 or 55-200. Tamron was much more helpful and between us we came up with a bunch of testing to isolate the issue (reset body, reset lens, new cards, etc). In the end it came down to the battery. With any of my three Nikon cells, if I get to less than 10% charge, the camera will randomly shoot two or three frames in burst, then lock up entirely, requiring me to pull the battery to restart. Then the top display will still show ERR and I have to switch to single shot for one exposure, producing no image, but one very loud metallic CLICK, then all is back to normal. As soon as I replace the battery, the issue disappears entirely. A further call to Nikon got a "never heard of such a thing" reply and, as all my batteries are the latest build, they do not qualify for replacement. The only bright side is that I am getting 1525+ shots on a charge, so I am pretty good to go with the three I have.

    Wasn't trying to do so. Your point was entirely valid since I didn't say which model of the lenses I was using in my original post.

    No worries. I actually appreciate having my theories shot down with hard facts.
