Fujifilm A150 has a
10.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Nikon S6100 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Expeed C2 processor.
Nikon S6100's sensor provides 6MP more than Fujifilm A150'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 A150 and S6100 sensor size comparison.
Sensor Size and Resolution Comparison image of Fujifilm A150 and Nikon S6100 Cameras
Fujifilm A150 and Nikon S6100 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 Fujifilm A150 has 59% larger pixel area compared to Nikon S6100, 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
Fujifilm A150
or the
Nikon S6100 ,
including hyperfocal distance.
