Samsung EX2F has a
12.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized BSI-CMOS sensor . On the other hand, Olympus XZ-1 has a
10.0MP 1/1.63-inch (8.07 x 5.56 mm ) sized CCD sensor and features TruePic V processor.
Below you can see the EX2F and XZ-1 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung EX2F and Olympus XZ-1 Cameras
Samsung EX2F and Olympus XZ-1 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 EX2F and Olympus XZ-1 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. Of the two cameras that we are comparing, EX2F has scored 48, 14 points higher than XZ-1.

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
Olympus XZ-1 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/1.7-inch versus 1/1.63-inch),
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.
