There are a few reports of the Canon EOS-1D X Mark III going to “sleep” briefly after taking a few shots with the camera. The autofocus points and camera information disappear from the viewfinder and the camera becomes unresponsive for a short time.
There have been a few reports of this as you can see throughout this DPReview thread.
There are also other reports of the camera going into sensor cleaning mode out of the blue and restarting.
Canon Rumors reader Hamilton sent us a video of the issue that you can watch above.
I expect that Canon will address these concerns very quickly.

They have so little joy in their lives....
Canon will get it sorted out. But the first step is that Canon have the ability to reproduce the issue themselves.
It makes me wonder why anybody would buy anything with software in it from a first production batch...
When they update the firmware, Canon please put an intervalometer in the darn thing, the battery and durability make it a second to none robust time-lapse tool.
A pro should probably not be using any new camera body in critical situations until the worst teething issues are corrected.
If the body passed testing, then there are other issues: Lens compatibility, exposure to high level RF radiation, exposure to high level X Rays at a port of entry, defective batteries, aliens.
AFAIK, firmware updates haven't fixed this, but maybe I missed something.
I should add that I've not seen it again, so one time that's it, I can not get it to do anything odd, the camera is awesome! Soooooo fast, no matter what state hit the shutter and its bang, powered up, metered, focused the shot is taken, no lag, no delay, instant, that's what I love about the 1D series, it's all about speed and this is truly the fastest camera I have ever owned.
I hope any issues are sorted and Canon bring more features to the Mk3, I have no problem buying a new camera and expect some minor bugs, with such a beast of a camera and such speed I guess minor issues are possible, I.e they can be overlooked or misses when they go into mass production.
