Samsung GX-1S has a
6.0MP APS-C (23.5 x 15.7 mm ) sized CCD sensor . On the other hand, Samsung NX300 has a
20.0MP APS-C (23.5 x 15.7 mm ) sized CMOS sensor and features DRIMe IV processor.
Samsung NX300's sensor provides 14MP more than Samsung GX-1S'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.
Below you can see the GX-1S and NX300 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung GX-1S and Samsung NX300 Cameras
Samsung GX-1S and Samsung NX300 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 GX-1S has 230% larger pixel area compared to Samsung NX300, 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 GX-1S
or the
Samsung NX300 ,
including hyperfocal distance.
