Nikon D4s has a
16.0MP Full frame (36 x 23.9 mm ) sized CMOS sensor and features Expeed 4 processor. On the other hand, Canon 1Ds has a
11.0MP Full frame (35.8 x 23.8 mm ) sized CMOS sensor .
Nikon D4s's sensor provides 5MP more than Canon 1Ds's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the D4s and 1Ds sensor size comparison.
Nikon D4s and Canon 1Ds 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
Both Nikon D4s and Canon 1Ds sensors have been tested by DxoMark. DxoMark 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. Of the two cameras that we are comparing, D4s has scored 89, 26 points higher than 1Ds.
