Kodak FZ55 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor . On the other hand, Olympus VG-145 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 FZ55 and VG-145 sensor size comparison.
Sensor Size and Resolution Comparison image of Kodak FZ55 and Olympus VG-145 Cameras
Kodak FZ55 and Olympus VG-145 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 Olympus VG-145 has 15% larger pixel area (2.04µm 2 vs 1.76µm 2 ) compared to Kodak FZ55, 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
Kodak FZ55
or the
Olympus VG-145 ,
including hyperfocal distance.
