Canon A480 has a
10.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Kodak FZ55 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor .
Kodak FZ55's sensor provides 6MP more than Canon A480's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the A480 and FZ55 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon A480 and Kodak FZ55 Cameras
Canon A480 and Kodak FZ55 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 Canon A480 has 59% larger pixel area compared to Kodak FZ55, it has potential to collect more light on pixel level hence 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
Canon A480
or the
Kodak FZ55 ,
including hyperfocal distance.
