Ricoh PX has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Smooth Imaging Engine IV processor. On the other hand, 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.
Below you can see the PX and EX-ZR100 sensor size comparison.
Sensor Size and Resolution Comparison image of Ricoh PX and Casio EX-ZR100 Cameras
Ricoh PX and Casio EX-ZR100 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 18% larger pixel area (2.34µm 2 vs 1.98µm 2 ) compared to Ricoh PX, 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
Ricoh PX
or the
Casio EX-ZR100 ,
including hyperfocal distance.
