Samsung NX3000 has a
20.0MP APS-C (23.5 x 15.7 mm ) sized CMOS sensor . On the other hand, Fujifilm X-T200 has a
24.0MP APS-C (23.5 x 15.7 mm ) sized CMOS sensor .
Below you can see the NX3000 and X-T200 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung NX3000 and Fujifilm X-T200 Cameras
Samsung NX3000 and Fujifilm X-T200 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 NX3000 has 20% larger pixel area compared to Fujifilm X-T200, 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 NX3000
or the
Fujifilm X-T200 ,
including hyperfocal distance.
