16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Smooth Imaging Engine IV processor.
Below you can see the S3500 and PX sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon S3500 and Ricoh PX Cameras
Nikon S3500 and Ricoh PX 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
Nikon S3500
or the
Ricoh PX ,
including hyperfocal distance.
