Canon 650D has a
18.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features Digic 5 processor. On the other hand, Samsung NX300M has a
20.0MP APS-C (23.5 x 15.7 mm ) sized CMOS sensor and features DRIMe IV processor.
Below you can see the 650D and NX300M sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 650D and Samsung NX300M Cameras
As seen above, Samsung NX300M has a 1.1x Larger sensor area than Canon 650D. 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
Canon 650D
or the
Samsung NX300M ,
including hyperfocal distance.
