Take a look at these photos of £5 note.

Both shot from exactly the same position on a tripod.

The Canon was using mirror lock up.

Canon 0M6A4945 iso 100, F/5.6, Tv 1/2000
Sony DSC00126 iso 100, F/4, Tv 1/4000

I guess the Canon should have been set to ISO 200 for correct comparison.

Set to ISO 200 as a concession to the Sony's lower light gathering performance?

I downloaded both images into tabs in a browser and then carefully clicked on the centre of one of the distinct, small features of the banknote which gave me identical, 100% views of the two images and the ability to switch instantly from one to the other. The Sony image is notably better than the Canon and the difference is largely one of contrast. Since both images are adequately exposed, and illuminated by enough light to drive both sensors out of noise domination, this seems to suggest that the ruling difference between the cameras is that the Sony has a notably superior lens.
