Fujifilm X-T30 has a
26.0MP APS-C (23.5 x 15.6 mm ) sized X-Trans CMOS sensor and features X-Processor 4 processor. On the other hand, Samsung NX30 has a
20.0MP APS-C (23.5 x 15.7 mm ) sized CMOS sensor and features DRIMeIV processor.
Fujifilm X-T30's sensor provides 6MP more than Samsung NX30's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Another difference between these two cameras is that Fujifilm X-T30's sensor lacks 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 X-T30 and NX30 sensor size comparison.
Sensor Size and Resolution Comparison image of Fujifilm X-T30 and Samsung NX30 Cameras
Fujifilm X-T30 and Samsung NX30 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 X-T30
or the
Samsung NX30 ,
including hyperfocal distance.
