Ricoh CX3 has a
10.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features Smooth Imaging Engine IV processor. On the other hand, Pentax RZ10 has a
14.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor .
Below you can see the CX3 and RZ10 sensor size comparison.
Sensor Size and Resolution Comparison image of Ricoh CX3 and Pentax RZ10 Cameras
Ricoh CX3 and Pentax RZ10 have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
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 CX3
or the
Pentax RZ10 ,
including hyperfocal distance.
