Samsung ST95 has a
16.0MP 1/2.3-inch (6.16 x 4.62 mm ) sized CCD sensor . On the other hand, Fujifilm A170 has a
10.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Samsung ST95's sensor provides 6MP more than Fujifilm A170'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 ST95 and A170 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung ST95 and Fujifilm A170 Cameras
Samsung ST95 and Fujifilm A170 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
Samsung ST95
or the
Fujifilm A170 ,
including hyperfocal distance.
