Samsung Galaxy NX has a
20.0MP APS-C (23.5 x 15.7 mm ) sized CMOS sensor and features DRIMe IV processor. On the other hand, Nikon D3500 has a
24.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features Expeed 4 processor.
One other difference between these two cameras that is worth mentioning is that Nikon D3500's sensor doesn't have an anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.
Below you can see the Galaxy NX and D3500 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung Galaxy NX and Nikon D3500 Cameras
Samsung Galaxy NX and Nikon D3500 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 Galaxy NX
or the
Nikon D3500 ,
including hyperfocal distance.
