The benefit of the extra 4 million pixels on the sensor of the APS-H format Canon EOS 1D Mark IV is plain to see here. There is a noticeable increase in detail resolution in this scene, which is most obvious in the finest areas, like the coin emblems and the etching on the portrait in the third crop from the top. Again, the smaller sensor and shorter lens have resulted in a wider depth of field in the image from the EOS 1D Mark IV, which explains why the paperclips and the toy dog's face are better defined, being slightly closer to the camera than the majority of the scene.

On the downside, at standard JPEG settings the EOS 1D Mark IV appears to be applying a little more sharpening than might be desirable for some scenes, which partly explains the impression of higher detail. A suggestion of haloing can be seen around some of the high contrast edges in this image, particularly in the fibres on the right of our robot, in the crop second from bottom.
