Samsung EX2F has a
12.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized BSI-CMOS sensor . On the other hand, Sony NEX-3N has a
16.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features Bionz processor.
Below you can see the EX2F and NEX-3N sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung EX2F and Sony NEX-3N Cameras
As seen above, Sony NEX-3N has a 8.8x Larger sensor area than Samsung EX2F. 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. Samsung EX2F and Sony NEX-3N sensors have been tested by DxO and the results show that NEX-3N has a better overall score of 74, 26 points higher compared to EX2F's score of 48.

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 EX2F
or the
Sony NEX-3N ,
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.
