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, Nikon D5200 has a
24.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features Expeed 3 processor.
Below you can see the NX300 and D5200 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung NX300 and Nikon D5200 Cameras
Samsung NX300 and Nikon D5200 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. Samsung NX300 and Nikon D5200 sensors have been tested by DxO and the results show that D5200 has a better overall score of 84, 8 points higher compared to NX300's score of 76.

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
Nikon D5200 ,
including hyperfocal distance.
