Casio EX-ZR800 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor and features EXILIM Engine HS 3 processor. On the other hand, Sony S2000 has a
10.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Bionz processor.
Casio EX-ZR800's sensor provides 6MP more than Sony S2000'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 EX-ZR800 and S2000 sensor size comparison.
Sensor Size and Resolution Comparison image of Casio EX-ZR800 and Sony S2000 Cameras
Casio EX-ZR800 and Sony S2000 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 Sony S2000 has 77% larger pixel area (3.13µm 2 vs 1.76µm 2 ) compared to Casio EX-ZR800, 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
Casio EX-ZR800
or the
Sony S2000 ,
including hyperfocal distance.
