Canon G12 has a
10.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized CCD sensor and features Digic 4 processor. On the other hand, Samsung EX2F has a
12.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized BSI-CMOS sensor .
Below you can see the G12 and EX2F sensor size comparison.
Sensor Size and Resolution Comparison image of Canon G12 and Samsung EX2F Cameras
Canon G12 and Samsung EX2F have the same sensor sizes so they will provide same level of control over the depth of field when used with 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. Canon G12 and Samsung EX2F sensors have been tested by DxO and the results show that EX2F has a better overall score of 48, 1 points higher compared to G12's score of 47.

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
Canon G12
or the
Samsung EX2F ,
including hyperfocal distance.
