Pentax K-01 has a
16.0MP APS-C (23.7 x 15.7 mm ) sized CMOS sensor . On the other hand, Samsung NX100 has a
15.0MP APS-C (23.4 x 15.6 mm ) sized CMOS sensor and features DRIMe Engine processor.
Below you can see the K-01 and NX100 sensor size comparison.
Sensor Size and Resolution Comparison image of Pentax K-01 and Samsung NX100 Cameras
Pentax K-01 and Samsung NX100 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 Pentax K-01 and Samsung NX100 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, K-01 has scored 79, 17 points higher than NX100.

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
Pentax K-01
or the
Samsung NX100 ,
including hyperfocal distance.
