Nikon S6300 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor . On the other hand, Pentax Efina has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Below you can see the S6300 and Efina sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon S6300 and Pentax Efina Cameras
Nikon S6300 and Pentax Efina 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 Pentax Efina has 15% larger pixel area (2.04µm 2 vs 1.76µm 2 ) compared to Nikon S6300, 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
Nikon S6300
or the
Pentax Efina ,
including hyperfocal distance.
