Got my 1dxIII for two weeks now, today was the first day to test the beast for a longer time, I'm coming from a 1dx.
Is there any body else who has the phenomenon that the body stops focusing? A restart of the body the focus continues. had it with my 100-400II +1.4x III once last week but I thought it was a user error. Today I got it twice in 700 shots with my 500 II + 1.4X III. Not yet tested it without the 1.4x. Will try tomorrow.
I tried my 200/1.8 with my 1DX3 last week in my house. Twice it completely froze with the image frozen on the screen and the lens not focusing. I turned the on/off switch to off then back on, but it didn’t turn the camera off. I had to remove the battery both times. This happened twice in about 300 shots over about five minutes. I assumed it was a connection error. I shot about 5000 photos the next day, many with that lens, with no issues.

Yes, it happened to me on the very first day. I turned camera off and on again and it has worked fine ever since. I have shot about 3500 images since then with no issue but now I am wondering and a bit concerned ...I had the 1.4 x and 600 v.3 on when it happened. Shot about 300 shots with that combo and all the rest of my shots are on the 600mm v.3 bare. I think I will test again with the 1.4 x on.
I have shot around 10K images with my 600iii with and without both version iii TCs. No issues on that lens.

No issues here. I used the 600mm Mk III today with both extenders, not a lot of pictures yet. I used the 400mm f2.8 with mainly a 2x or stacked extenders, the 400mm DO II and 200-400mm all without issue. On another forum someone mentioned their 500mm version 1 was having issues.
When ever this has happened to me (on other bodies) I was indoors and trying to focus outside the range of the focus distance switch. BTW, new bodies in low light sometimes refuse to focus at all.

Check the "Lens drive when AF impossible" in the AF menu, make sure it is set to ON.
Yes, I checked that when it happened and it is set to "ON".

I used those lens combinations a lots with my 1Dx with no issues.
So it is 1Dxiii specific!
I had this happen tonight with my 1DX3 and 600iii. I can’t remember if I had a TC on or not. I was shooting through the OVF. I went at least five seconds with no response from the focusing system. I turned the camera off and on and then it worked fine for the rest of the session. This was different from what happened with my 200/1.8 in which the entire camera froze in live view.
Has happened with my 1DxII, normally at the most inopportune times. Turn it off, quick pull of the battery and it rolls again. Has happened with my 300II and 70-200II.
I had this 100-400v1 with questionable IS. The lens would lockup my 20D from time to time and the only way to fix it was through battery removal. Using the same lens on my friend's 30D, the in camera display would flash from time to time, I supposed the 30D was undergoing some sort of soft reset, no battery removal was needed.
The problem went away after I upgraded to 5D2. I guess Canon identified the problem and fixed the issue on all the Canon bodies. The problem was associated with my 100-400v1 as I did not see it in all my other lens.
Happens to me randomly; I just hit the lens release, slightly rotate then remount and its good to go. Don't need to switch off/remove battery. Seems like a firmware issue
FYI, For any situation where you have to remove the battery before the camera recovers that usually means the firmware went off into the weeds and is hung somehwere, ie a software bug. This is because most cameras are designed to require firmware intervention before the camera is allowed to be turned off (even if you switch it to off) - this is to give firmware the opportunity to save all the current settings and shooting parameters (they aren't saved in realtime) and also to allow firmware time to complete the flushing of any buffered images. If firmware is hung up somewhere it wont be able to respond to the internal interrupt triggered by the power-off request, thus requiring you to pull the battery to recover.
