Ricoh PX has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Smooth Imaging Engine IV processor. On the other hand, Samsung WB750 has a
13.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor .
Below you can see the PX and WB750 sensor size comparison.
Sensor Size and Resolution Comparison image of Ricoh PX and Samsung WB750 Cameras
Ricoh PX and Samsung WB750 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 Samsung WB750 has 12% larger pixel area (2.23µm 2 vs 1.98µm 2 ) compared to Ricoh PX, 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
Ricoh PX
or the
Samsung WB750 ,
including hyperfocal distance.
