12.0MP APS-C (23.6 x 15.8 mm ) sized CMOS sensor and features Expeed processor.
Below you can see the GX-20 and D300 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung GX-20 and Nikon D300 Cameras
Samsung GX-20 and Nikon D300 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.
DxOMark Sensor Scores
Both Samsung GX-20 and Nikon D300 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.

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
Samsung GX-20
or the
Nikon D300 ,
including hyperfocal distance.
