Canon 1Ds MII has a
17.0MP Full frame (36 x 24 mm ) sized CMOS sensor . On the other hand, Nikon D4 has a
16.0MP Full frame (36 x 23.9 mm ) sized CMOS sensor and features Expeed 3 processor.
Below you can see the 1Ds MII and D4 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 1Ds MII and Nikon D4 Cameras
Canon 1Ds MII and Nikon D4 have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
DxOMark Sensor Scores
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Canon 1Ds MII and Nikon D4 sensors have been tested by DxO and the results show that D4 has a better overall score of 89, 15 points higher compared to 1Ds MII's score of 74.

Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Canon 1Ds MII
or the
Nikon D4 ,
including hyperfocal distance.
