Sensor Size and Resolution Comparison image of Samsung NX210 and Canon R50 Cameras
As seen above, Samsung NX210 has a 1.1x Larger sensor area than Canon R50. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in 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 NX210
or the
Canon R50 ,
including hyperfocal distance.
