I would like to see a photo...

May not be able to name the camera models involved... If you have an image from a 40D that is indistinguishable from that made with a 5D3, I know somebody screwed up with the 5D3. I presume that most folks in this forum who have owned more than one camera, especially cameras from different generations, can see the difference between the two.
