Ricoh WG-20 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Kodak WPZ2 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor .
Below you can see the WG-20 and WPZ2 sensor size comparison.
Sensor Size and Resolution Comparison image of Ricoh WG-20 and Kodak WPZ2 Cameras
Ricoh WG-20 and Kodak WPZ2 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 Ricoh WG-20 has 15% larger pixel area compared to Kodak WPZ2, 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
Ricoh WG-20
or the
Kodak WPZ2 ,
including hyperfocal distance.
