Panasonic SZ5 has a
14.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Ricoh CX4 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.
Below you can see the SZ5 and CX4 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic SZ5 and Ricoh CX4 Cameras
Panasonic SZ5 and Ricoh CX4 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
Panasonic SZ5
or the
Ricoh CX4 ,
including hyperfocal distance.
