Casio EX-ZR1000 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, Canon SX240 HS has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features Digic 5 processor.
Below you can see the EX-ZR1000 and SX240 HS sensor size comparison.
Sensor Size and Resolution Comparison image of Casio EX-ZR1000 and Canon SX240 HS Cameras
Casio EX-ZR1000 and Canon SX240 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 Canon SX240 HS has 32% larger pixel area (2.34µm 2 vs 1.76µm 2 ) compared to Casio EX-ZR1000, 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-ZR1000
or the
Canon SX240 HS ,
including hyperfocal distance.
