Panasonic S2 has a
14.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Samsung Galaxy Camera has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features 1.4GHz Quad-Core processor.
Below you can see the S2 and Galaxy Camera sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic S2 and Samsung Galaxy Camera Cameras
Panasonic S2 and Samsung Galaxy Camera 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.
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
Panasonic S2
or the
Samsung Galaxy Camera ,
including hyperfocal distance.
