Samsung NX1000 has a
20.0MP APS-C (23.5 x 15.7 mm ) sized CMOS sensor . On the other hand, Fujifilm X-T100 has a
24.0MP APS-C (23.5 x 15.7 mm ) sized CMOS sensor .
Below you can see the NX1000 and X-T100 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung NX1000 and Fujifilm X-T100 Cameras
Samsung NX1000 and Fujifilm X-T100 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. On the other hand, since Samsung NX1000 has 20% larger pixel area compared to Fujifilm X-T100, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
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
Fujifilm X-T100 ,
including hyperfocal distance.
