12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Below you can see the FE-25 and EX-Z400 sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus FE-25 and Casio EX-Z400 Cameras
Olympus FE-25 and Casio EX-Z400 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
Olympus FE-25
or the
Casio EX-Z400 ,
including hyperfocal distance.
