Panasonic FH10 has a
16.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Samsung SL102 has a
10.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor .
Panasonic FH10's sensor provides 6MP more than Samsung SL102'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 FH10 and SL102 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic FH10 and Samsung SL102 Cameras
Panasonic FH10 and Samsung SL102 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 Samsung SL102 has 59% larger pixel area (2.78µm 2 vs 1.74µm 2 ) compared to Panasonic FH10, 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
Panasonic FH10
or the
Samsung SL102 ,
including hyperfocal distance.
