Casio EX-Z550 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Canon SX510 HS has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor and features Digic 4 processor.
Below you can see the EX-Z550 and SX510 HS sensor size comparison.
Sensor Size and Resolution Comparison image of Casio EX-Z550 and Canon SX510 HS Cameras
Casio EX-Z550 and Canon SX510 HS 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-Z550 has 14% larger pixel area compared to Canon SX510 HS, 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-Z550
or the
Canon SX510 HS ,
including hyperfocal distance.
