Samsung WB2200F has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor . On the other hand, Kodak M381 has a
12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor .
Below you can see the WB2200F and M381 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung WB2200F and Kodak M381 Cameras
Samsung WB2200F and Kodak M381 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
Samsung WB2200F
or the
Kodak M381 ,
including hyperfocal distance.
