Panasonic S3 has a
14.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor and features Venus Engine IV processor. On the other hand, Olympus SP-620 UZ has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features TruePic III+ processor.
Below you can see the S3 and SP-620 UZ sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic S3 and Olympus SP-620 UZ Cameras
Panasonic S3 and Olympus SP-620 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 S3
or the
Olympus SP-620 UZ ,
including hyperfocal distance.
