Samsung NX300 has a
20.0MP APS-C (23.5 x 15.7 mm ) sized CMOS sensor and features DRIMe IV processor. On the other hand, Canon 1D MIV has a
16.0MP APS-H (27.9 x 18.6 mm ) sized CMOS sensor and features Digic 4 processor.
Below you can see the NX300 and 1D MIV sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung NX300 and Canon 1D MIV Cameras
As seen above, Canon 1D MIV has a 1.4x Larger sensor area than Samsung NX300. 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 Samsung NX300 and Canon 1D MIV 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, NX300 has scored 76, 2 points higher than 1D MIV.

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
Samsung NX300
or the
Canon 1D MIV ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(APS-C versus APS-H),
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.
