Sony QX1 has a
20.0MP APS-C (23.2 x 15.4 mm ) sized CMOS sensor and features Bionz X processor. On the other hand, Nikon D5100 has a
16.0MP APS-C (23.6 x 15.7 mm ) sized CMOS sensor and features Expeed 2 processor.
Below you can see the QX1 and D5100 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony QX1 and Nikon D5100 Cameras
Sony QX1 and Nikon D5100 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
Sony QX1
or the
Nikon D5100 ,
including hyperfocal distance.
