I think I may have discovered my problem. First, the camera is affected by the service advisory, so I'll probably need to send it in anyway.

But, here is what I've found:
I was testing the AF with my 3 AF lenses (Sigma 35, 100-400, and 500 f/4). The Sigma was focusing very erratically and not at all near the mfd. And the 500 wasn't focusing at all. But, the 100-400 seemed OK. So, I also tried the Sigma on my 5D III and got much the same bad behavior.

But, why wouldn't the 500mm focus at all? Then it hit me...I was testing the 500mm with the 2x III attached. Removing the 2x and using the lens bare or with the 1.4x seems to work fine. Then I looked and the firmware on the 1DX doesn't appear to have ever been updated. It was only a recent firmware update that allowed the 1DX and 5D III to AF with f/8 lenses. Updating the firmware will probably put things right.

My sincere apologies Clemson656 for being a dummy, but it's taken me all evening to understand why my new-to-me 1DX was having AF issues. I'm working on the firmware update and I'll report back. I'm optimistic.

So glad to hear that you figured out the problem.

I didn't update the firmware as I've heard people having issues with it. So, if it ain't broke, don't fix it, right? :)

Anyway, Canon will take care of it free of charge if you want to send it in. Just give them a call.

Enjoy the camera. I'll miss it for sure. Cheers.

P.S. Canon would send a shipping label for this issue with 1DX, but they refused to provide a free shipping label if I want to send my 200/2L in for the issue it has with my 5D3. :(

Success! And a huge sigh of relief. The firmware has been updated to 1.2.4 and the 1DX now successfully auto-focuses the 500mm + 2x III. :D

Clemson656's claims about the condition of the camera were spot on: it is in superb condition and my AF woes turned out to be my user error along with a Sigma lens that is misbehaving on both 1DX or 5D III. He is a great seller. As a buyer, though, I didn't do so well tonight. :oops:

Now about the images: Wow. I am very pleased and highly impressed with high ISO performance.

Glad to read you got most of your issues sorted David. I'm interested in hearing what the problem is/was with the Sigma 35 since I have one too along with a 5D3. Looking forward to seeing some of your shots using your new to you 1DX.

I think I've figured out the root of all problems--I didn't have a Canon super-telephoto lens with a 2x III to use. If I had such a pair, I would have updated my cameras including the 1DX to have the newest firmware. That way, this wouldn't have happened. :D

Now, is that a good reason to tell my wife I need a super-telephoto? LOL

Anyway, I'm very glad that you're now happy with it. I'll miss it for sure.

It's just not focusing consistently anwhere close to the MFD. Ten feet out and more and it's better. But, closer in and the AF just sits there whirring, but not focusing. My Zeiss 35mm never has that problem! ;)

:lol: Absolutely; now you've got all the logical ammunition you need to get a really long lens! :lol: Thanks for the well-wishes; I am so looking forward to my outing to the wildlife refuge this weekend.

Here's a quick vid of around 50 strikes that happened during the two hours we were out! Two different camera angles so the light shifts. Same storm the above pics came from. And this is not all the lightning that happened during our time out there! Missed quite a few adjusting the cameras or ducking!!
