Panasonic ZS30 has a
18.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor . On the other hand, Ricoh WG-20 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Below you can see the ZS30 and WG-20 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic ZS30 and Ricoh WG-20 Cameras
Panasonic ZS30 and Ricoh WG-20 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 30% larger pixel area (2.04µm 2 vs 1.56µm 2 ) compared to Panasonic ZS30, 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
Panasonic ZS30
or the
Ricoh WG-20 ,
including hyperfocal distance.
