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. On the other hand, Samsung NX11 has a
15.0MP APS-C (23.4 x 15.6 mm ) sized CMOS sensor and features DRIM Engine processor.
Below you can see the X70 and NX11 sensor size comparison.
Sensor Size and Resolution Comparison image of Fujifilm X70 and Samsung NX11 Cameras
Fujifilm X70 and Samsung NX11 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
Fujifilm X70
or the
Samsung NX11 ,
including hyperfocal distance.
