Kodak FZ45 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor . On the other hand, Casio EX-FS10 has a
9.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor .
Kodak FZ45's sensor provides 7MP more than Casio EX-FS10'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 FZ45 and EX-FS10 sensor size comparison.
Sensor Size and Resolution Comparison image of Kodak FZ45 and Casio EX-FS10 Cameras
Kodak FZ45 and Casio EX-FS10 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 Casio EX-FS10 has 77% larger pixel area (3.13µm 2 vs 1.76µm 2 ) compared to Kodak FZ45, 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 FZ45
or the
Casio EX-FS10 ,
including hyperfocal distance.
