Canon A1400 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Casio EX-H15 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Below you can see the A1400 and EX-H15 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon A1400 and Casio EX-H15 Cameras
Canon A1400 and Casio EX-H15 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-H15 has 14% larger pixel area (2.01µm 2 vs 1.76µm 2 ) compared to Canon A1400, 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
Canon A1400
or the
Casio EX-H15 ,
including hyperfocal distance.
