Samsung NX1000 has a
20.0MP APS-C (23.5 x 15.7 mm ) sized CMOS sensor . On the other hand, Pentax ist DS2 has a
6.0MP APS-C (23.5 x 15.7 mm ) sized CCD sensor .
Samsung NX1000's sensor provides 14MP more than Pentax ist DS2'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 NX1000 and ist DS2 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung NX1000 and Pentax ist DS2 Cameras
Samsung NX1000 and Pentax ist DS2 have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture.
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 NX1000
or the
Pentax ist DS2 ,
including hyperfocal distance.
