Casio EX-FS10 has a
9.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor . On the other hand, Kodak M530 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Below you can see the EX-FS10 and M530 sensor size comparison.
Sensor Size and Resolution Comparison image of Casio EX-FS10 and Kodak M530 Cameras
Casio EX-FS10 and Kodak M530 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 33% larger pixel area compared to Kodak M530, 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
Casio EX-FS10
or the
Kodak M530 ,
including hyperfocal distance.
