I saw this "dark ring" issue with my 5D3 today.
I was shooting daffodils etc. in sunlight against dark backgrounds. I was shooting RAW + JPG.
Got them home, and saw dark borders around bright parts of flower petals etc.
Since I'd been shooting RAW too, I tried re-processing in camera and turned sharpness down to minimum and created another JPG.
Looked at that on the computer and the dark border was gone.
So I've reduced the sharpness setting on the camera now.
I don't think the pixel binning is an issue with the 5DIII, the 22.3MP works out to be 1920 x 1080 when divided.
