Panasonic LX7 has a
10.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized CMOS sensor and features Venus Engine processor. On the other hand, Nikon D2Xs has a
12.0MP APS-C (23.7 x 15.7 mm ) sized CMOS sensor .
Below you can see the LX7 and D2Xs sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic LX7 and Nikon D2Xs Cameras
As seen above, Nikon D2Xs has a 9.0x Larger sensor area than Panasonic LX7. 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
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It 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. Panasonic LX7 and Nikon D2Xs sensors have been tested by DxO and the results show that D2Xs has a better overall score of 59, 9 points higher compared to LX7's score of 50.

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
Panasonic LX7
or the
Nikon D2Xs ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/1.7-inch versus APS-C),
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.
