Sony G3 has a
10.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Samsung WB1100F has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Samsung WB1100F'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 G3 and WB1100F sensor size comparison.
Sensor Size and Resolution Comparison image of Sony G3 and Samsung WB1100F Cameras
Sony G3 and Samsung WB1100F 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 compared to Samsung WB1100F, it has potential to collect more light on pixel level hence 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
Sony G3
or the
Samsung WB1100F ,
including hyperfocal distance.
