Nikon 1 J2 has a
10.0MP 1-inch (13.2 x 8.8 mm ) sized CMOS sensor and features Expeed 3 processor. On the other hand, Pentax Q10 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor .
Below you can see the 1 J2 and Q10 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon 1 J2 and Pentax Q10 Cameras
As seen above, Nikon 1 J2 has a 4.1x Larger sensor area than Pentax Q10. 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.
DxOMark Sensor Scores
Both Nikon 1 J2 and Pentax Q10 sensors have been tested by DxoMark. DxoMark scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Of the two cameras that we are comparing, 1 J2 has scored 54, 5 points higher than Q10.

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
Nikon 1 J2
or the
Pentax Q10 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1-inch 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.
