Samsung NX5 has a
15.0MP APS-C (23.4 x 15.6 mm ) sized CMOS sensor and features DRIM Engine processor. On the other hand, Canon 550D has a
18.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features Digic 4 processor.
Below you can see the NX5 and 550D sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung NX5 and Canon 550D Cameras
Samsung NX5 and Canon 550D 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 NX5
or the
Canon 550D ,
including hyperfocal distance.
