When I shoot JPEG with my 1D-X and Sigma art lenses, I get dark rings around the JPEGs. I shoot both raw and JPEG, and when the CR2 converts to a DNG format, the rings disappear. But no matter what settings I use, the JPEGs are unusable, and I can't find anything in Photoshop or Lightroom to remove the rings. Can someone tell me what's wrong and how to repair it? I get otherwise gorgeous pictures with the Sigmas. I included a test image below:

Do you have any of the in-camera processing options checked, like peripheral illumination corrrection?

"I get dark rings around the JPEGs."
Are you referring to the 'target' shaped dark rings?
"When I shoot JPEG with my 1D-X and Sigma art lenses,..."
The obvious question, does it happen with all your lenses? This will tell me if it is a lens or camera problem. BTW, there is nothing I know of in LR or PS that will remove them except manual labor!

That resembles a double exposure of the third kind.
