Casio EX-H30 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Exilim Engine 5.0 processor. On the other hand, Casio EX-H10 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Below you can see the EX-H30 and EX-H10 sensor size comparison.
Sensor Size and Resolution Comparison image of Casio EX-H30 and Casio EX-H10 Cameras
Casio EX-H30 and Casio EX-H10 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-H10 has 32% larger pixel area (2.34µm 2 vs 1.76µm 2 ) compared to Casio EX-H30, 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-H30
or the
Casio EX-H10 ,
including hyperfocal distance.
