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. On the other hand, Panasonic FZ200 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor and features Venus Engine VII FHD processor.
Below you can see the SP-620 UZ and FZ200 sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus SP-620 UZ and Panasonic FZ200 Cameras
Olympus SP-620 UZ and Panasonic FZ200 have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since Panasonic FZ200 has 32% larger pixel area (2.34µm 2 vs 1.76µm 2 ) compared to Olympus SP-620 UZ, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.
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 SP-620 UZ
or the
Panasonic FZ200 ,
including hyperfocal distance.
