Casio EX-ZR100 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features Exilim Engine HS processor. On the other hand, Olympus SZ-30MR has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor and features TruePic III+ processor.
Below you can see the EX-ZR100 and SZ-30MR sensor size comparison.
Sensor Size and Resolution Comparison image of Casio EX-ZR100 and Olympus SZ-30MR Cameras
Casio EX-ZR100 and Olympus SZ-30MR 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-ZR100 has 32% larger pixel area compared to Olympus SZ-30MR, 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-ZR100
or the
Olympus SZ-30MR ,
including hyperfocal distance.
