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, Samsung NX2000 has a
20.0MP APS-C (23.5 x 15.7 mm ) sized CMOS sensor .
Below you can see the D4s and NX2000 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon D4s and Samsung NX2000 Cameras
As seen above, Nikon D4s has a 2.3x Larger sensor area than Samsung NX2000. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
DxOMark Sensor Scores
Both Nikon D4s and Samsung NX2000 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, 14 points higher than NX2000.

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
Nikon D4s
or the
Samsung NX2000 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(Full frame versus APS-C),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
