Panasonic ZS3 has a
10.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Olympus SP-800 UZ has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features TruePic III processor.
Below you can see the ZS3 and SP-800 UZ sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic ZS3 and Olympus SP-800 UZ Cameras
Panasonic ZS3 and Olympus SP-800 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
Panasonic ZS3
or the
Olympus SP-800 UZ ,
including hyperfocal distance.
