Right... Its a $3500 camera and he is seeing a problem. For a camera, a bad sensor is pretty much the worst thing.

On the other hand, I dont see any banding/noise in the sizes I looked at. Some noise on a Canon sensor is expected in the darkest shadows.

+1, CWB does help if you really need to take the wider DR & fast lens shot. 5Dc (12 bit) seem to handle a little better than 5D2/3 (14 bit) when shooting against the light. 5D2 is the worse of three in this case.

TLA alert!

Custom White Balance (CWB) only helps with in-camera JPEGs. When you shoot Raw, no white balance setting affects the pixels. With Raw, a CWB can make the HistoBlinkyMeter (histogram + blinkies) a little more accurate, but no pixels are affected because white balance is set during Raw conversion.

I said: "help" not "fixed it"....

"TLA alert! ", you seem really GOOD at these type of post

YOU might want to add and/or verify some of your nonsense response to Ander's list.

I suspect that the camera is not defective. The way to check is to make some side by side shots with someone who has the same camera.

Calgary is a large enough city that somebody on FM in Calgary with a 5D3 must be willing to help out.

If you make shots with the same lens from the same position (two carefully aligned tripods or one tripod with the two cameras aligned by checking the corners of the frame in the viewfinder) with the same ISO, shutter speed, an aperture, then you'll be able to look for differences.

If your technique is really

Now, what is your position regarding of 5d2/3... canon low iso wide DR shadows chroma noise & banding noise issues, your honest opinion please
