Both Samsung EX2F and Olympus 1s have 12.0 MP resolution sensors but Samsung EX2F's sensor is 1/1.7-inch (7.44 x 5.58 mm ) and Olympus 1s's sensor is 1/1.7' (7.44 x 5.58 mm ).
Since Olympus 1s's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Samsung EX2F.
Below you can see the EX2F and 1s sensor size comparison.

Samsung EX2F and Olympus 1s 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.
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 1s ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/1.7-inch versus 1/1.7' ),
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.
