Nikon S800c has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features Expeed C2 processor. On the other hand, Sony G3 has a
10.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Nikon S800c's sensor provides 6MP more than Sony G3's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the S800c and G3 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon S800c and Sony G3 Cameras
Nikon S800c and Sony G3 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 Sony G3 has 59% larger pixel area (2.81µm 2 vs 1.76µm 2 ) compared to Nikon S800c, 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 S800c
or the
Sony G3 ,
including hyperfocal distance.
