Samsung NX10 has a
15.0MP APS-C (23.4 x 15.6 mm ) sized CMOS sensor and features DRIM Engine processor. On the other hand, Fujifilm X70 has a
16.0MP APS-C (23.6 x 15.6 mm ) sized CMOS X-TRANS II sensor and features EXR Processor II processor.
Below you can see the NX10 and X70 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung NX10 and Fujifilm X70 Cameras
Samsung NX10 and Fujifilm X70 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.
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 NX10
or the
Fujifilm X70 ,
including hyperfocal distance.
