Fujifilm S4200 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Olympus SP-600 UZ has a
12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor and features TruePic III processor.
Below you can see the S4200 and SP-600 UZ sensor size comparison.
Sensor Size and Resolution Comparison image of Fujifilm S4200 and Olympus SP-600 UZ Cameras
Fujifilm S4200 and Olympus SP-600 UZ 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
Fujifilm S4200
or the
Olympus SP-600 UZ ,
including hyperfocal distance.
