Panasonic GX85 has a
16.0MP Four Thirds (17.3 x 13 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 .
Another difference between these two cameras is that Panasonic GX85's sensor lacks anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.
Below you can see the GX85 and D2Xs sensor size comparison.
As seen above, Nikon D2Xs has a 1.7x Larger sensor area than Panasonic GX85. 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.
