Not thrilled to report, but I can be inducted to the crap on the 1DX sensor club. I have tried to blow it off, but the yuc still prevails. Mine is not nearly as bad as that shown by the OP, but it is bad enough. Mine shows mostly on the top half of the picture and more toward the left side(so bottom left of the sensor). The body has about 2000 clicks and has never had the lens changed outdoors.
No big deal, but frustrating obviously. And yes, I expect more from a 1DX than I would from a rebel.

That is also about where I see the most dust in my images. It's a ton of very small, relatively faint spots. Way more than I have on my 'dust magnet' Leica M9 CCD sensor... which I rarely clean despite frequent lens changes in all sorts of conditions.
I have never had to send one thing back to the original manufacturer. My local shop will clean mine for free, but is there something going on than Canon needs to see? But, at my local shop they will do it while I wait, I wonder how long canon will take to have mine back in hand??

If you take a blower and use it on the sensor and nothing moves then it's between some things in there. I would use the artic blower on the entire sensor and then shoot at f/22 again none of the little ones moved at all. It's not regular dust issues, the big ones moved and can be cleaned but the little ones are trapped and will not move.

Oh I just emailed them about this. I didn't buy this to send it in to be cleaned though and if it were just dust then I would just clean it myself but this isn't dust. I wonder if anyone else has these issues.
My 1Dmk4 had sensor oil spots right from the start. Just recently I had to send it in to CPS for a shutter replacement so I asked them to clean the oil spots off the sensor as well. I know its a ball ache, but for your peace of mind and reduced stress level it's worth sending in It's possible that by trying to clean it yourself you might smear the oil (if it is oil) instead of removing it.

I believe the image is reversed of the position on the sensor so dust/oil in one corner of the image is in the opposite corner on the sensor. Someone please correct me if I have that wrong.
That is correct. Looking directly at the sensor top is bottom and left is right. It's completely flipped.

This is a standard feature with Nikon pro cameras.... maybe Canon now thinks their users want it too?
Maybe the idiots who are having fun with this could read page 2 and a Tech's explanation of the issue instead of thinking it was a simple dust problem.
A Nikon D3 I owned was not only a dust magnet, but lacked sensor cleaning built in. It sucked. That and oil splatter made it impossible to clean. Wet cleaning, sensor swabs, it defied cleaning. All it did was smear.
Once I moved back to Canon and their built in cleaning, I've never cleaned a sensor again. And I do change lenses in all kinds of conditions. Maybe I've not looked close enough, but having readily seen those dust bunnies before, I'm certain I'd see them now if they were there.
What you've shown is completely unacceptable and needs to go to Canon for a cleaning.
On a lighter note, it wasn't that long ago that sensors didn't self clean and we all had to be proficient swabbers. In the Canon 10D and 1Ds days I just kept the sensor cleaning stuff out on the desk all the time as it was such a frequent thing.
Recently cleaned my 5D3 with similar dust amount using Eclipse/FF swabs remained since 5D classic dust monster time Took 3 swabs to clean but fine now. Is it a problem for you?

Maybe next time you'll know to send your gear to Canon when you have a repair issue, instead of expecting a forum rant to magically solve the problem?

About lots dust on your sensor, what else? I this your first slr? It would be same as if I would get flat tire on my car and complain on forum that for this money I paid for car - nails should not get into tire ...

May be dust just forget to read that memo and stay away of your 1dX since you paid so much money for it?

Your talking about this.
"This from Canon Technician "Your product has been examined and it was found that there was a foreign object in the imaging sensor assembly "
I emailed CPS about this asking a question and their response was
"I think they wording of the note might tell us what happened here. The technician's note specifically states that there was "...a foreign object in the imaging sensor assembly..." (emphasis mine) so I can only assume that this means it was caught in between the cleaning unit and the sensor. This would definitely explain why you would not have been able to blow the dust free, and why the cleaning unit was unable to vibrate the dust off either. Of course, this is an assumption that I am making based on the technician's notes, but it definitely fits the symptoms you were seeing. "
The cleaning unit being part of the "image sensor assembly" and the fact that you did not do a wet swipe that dose not mean that the spots on the sensor were necessarily behind anything. So the Idiots could be right and your assumption just fits your theory and you had the courage to clean the thing yourself with a swab you would see the idiots may not be idiots. Its entirely possible that you are the idiot. I suggest you never change the lens again so you won't blow a fuse.
I hope nobody use soap and water as a cleaning method in the 1DX.
It's possible that by trying to clean it yourself you might smear the oil (if it is oil) instead of removing it.
