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, Sony QX10 has a
18.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor .
Below you can see the QX1 and QX10 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony QX1 and Sony QX10 Cameras
As seen above, Sony QX1 has a 12.7x Larger sensor area than Sony QX10. 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
Sony QX1
or the
Sony QX10 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(APS-C versus 1/2.3-inch),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
