This is close to the f/8 full-frame shot taken by the 5D at f/8. The center of the image is "the same" as the cropped version above, but obviously this image has been shrunken down to the same size as the cropped-sensor image. You will note that the image seems to have "more depth of field" than the two cropped versions due to the viual affect of the shrinking. This has the same affect as viewing an image from a greater distance: things appear sharper. This is what people refer to as "perceived" depth of field, because it squeezes a wider field of view into the same viewing size as the cropped sensor and is then perceived to have a deeper DOF, although when the original image is viewed at the same magnification as the cropped-sensor image you see that the "actual" DOF is the same.

You would have a different affect if you moved the full-sensor camera closer to the subject or used a longer lens, to get the same field of view as the cropped sensor: you would make your actual field of view more shallow.
