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, Fujifilm X-A5 has a
24.0MP APS-C (23.5 x 15.7 mm ) sized CMOS sensor .
Below you can see the Galaxy NX and X-A5 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung Galaxy NX and Fujifilm X-A5 Cameras
Samsung Galaxy NX and Fujifilm X-A5 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 Galaxy NX has 20% larger pixel area compared to Fujifilm X-A5, 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 Galaxy NX
or the
Fujifilm X-A5 ,
including hyperfocal distance.
