Kodak WPZ2 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor . On the other hand, Ricoh G700SE has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Below you can see the WPZ2 and G700SE sensor size comparison.
Sensor Size and Resolution Comparison image of Kodak WPZ2 and Ricoh G700SE Cameras
Kodak WPZ2 and Ricoh G700SE 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 G700SE has 32% larger pixel area (2.34µm 2 vs 1.76µm 2 ) compared to Kodak WPZ2, 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
Kodak WPZ2
or the
Ricoh G700SE ,
including hyperfocal distance.
