Having been through exactly this situation (with Jeff's kind assistance) and seeing how this has been a problem for Jeff for some time, I don't think any of the typical suggestions are going to yield much in the way of results. My only offerings would be to try turning completely off the sensor cleaning from the menu (I think you can) and if that doesn't work (I doubt that it will), just sell the camera.
Dumping my piece o' s@*t 1DMkIII was the best thing I have done photographically in a very long time. My mood improved dramatically, I don't constantly wonder if important shots are screwed up and even though it was very expensive moving up to a 1DsMkIII, it turned out to be significantly cheaper as having a camera that can actually focus has yielded images that have produced more income than the price difference.
I am convinced that if you have a bad 1DMkIII then the only option is to get rid of it. The good ones may be very good but it is hard for people who have not experienced it to understand just how bad the bad ones are.
i too got rid of my 1d III. stuck with the 5d. with any luck, something decent (full-frame, good AF), that doesn't cost an exorbitant $8000, will come along from canon in the next several months.
I had a bunch of weird shots from my 24-70L last wedding, the left side was ok, the right side was horribly smeared on the same plane of focus, it only happened about 5 times (very bright light) but I've had it before often in fluorescent lighting. Rest of the time it's pretty incredible.

Oh, this is on 5D's...
Wow, let's start a series of threads on the problems of the 5D before the successor is introduced! First I've heard of this one.

I have a mint condition, low actuation 1D that has never shown any problems. I will trade it for the OP's 1DIII. I like a challenge, and will do whatever is necessary to turn that camera into a properly functioning sample.
Seriously, responding to Jeff, I'm sorry once again to hear about all the problems you've had with your 1DIII bodies. Pretty amazing story.
It seem like most of your ghosting images are from the result of your lens being wide open at f/2.8. In general most lenses are softer wide open, specially zoom lenses. You have to stop down your to f/4 to 5.6 to sharpen it up. Thats true with my 70-200mmL and 24-70mm, so i traded it for a 200mmL. At f/2.8 my 200mmL was as sharp as f/8. It was tnight and day. I don't think its your MKIII, i think its your lens.
Currently i use a MKIIn and i'm happy with it. Theres no issues what so ever. (Knock on wood). The only thing i wished it had was a bigger Raw buffer. I personnally waititng for the MKIIIn. I think it will be a refined MKIII with no focusing issues ( BLue Dot Crap etc.

I occasionally see photos like Jeff's from my 1DIII also. It's an early serial number body and had all the repairs and upgrades from Canon. For the most part it does ok now but I see those weird ghosted ones too. I'm not sure it's an AF issue, but I can't explain it.
None of you other people see photos like that? Ever? Maybe only certain bodies are affected. Jeff's replacement is a newer one. Whatever the cause, apparently Canon still doesn't have a handle on it.
I guess that's why a number of people feel they just couldn't trust the MkIII, and gave up.

I think you should go back and look at his photo`s and read his posts before you make a reply like this.......did you even look at them some 2.8`s are sharp but different focal length

Don't you have any suggestion to the thread that can help rather than criticize others. I have read the thread and seen the images. As far as i can see Jeff has only used one lens. 24-70mmL (A lens i have owned before and had similar results like his images). Who care about diffrent focal lengths, it still the same lens! There is a thing called "process of elimination" I own alot of "L" lenses and i can tell you i've done countless testing with lenses wide open vs. stopped down one or two stops and the the result is totally diffrent. Everyone is so fast to accuse the MKIII for focusing problems and not even check the lens.

Thats because most working pros have multiple bodies and shoot for so long with the gear that we KNOW our gear very well. If it was the lens he would see it everywhere.
Its not the lens, its his body, ghosting is a documented problem. Documented on tgis forum at least.

The "ghosting" is caused by the body and not the lens, however, it doesn't appear to be related to the AF either. It happens once in a blue moon and cannot be repeated. A lot of people speculate that it is more the dust shaking mechanism is the culprit. I tend to believe that it is true.

My feeling would be that it is a focus problem within the body. A problem with the anti-dust feature would logically appear with any lens from a little 24L prime to a 400/2.8 IS.

I think what some are saying is what I said earlier. All the shots in bad focus are with the 24-70L. It could be the lens. We're just trying to eliminate that by seeing if it happens with other lenses.
