Panasonic ZS70 has a
20.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features Venus Engine processor. On the other hand, Casio EX-FH100 has a
10.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor .
Panasonic ZS70's sensor provides 10MP more than Casio EX-FH100'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 ZS70 and EX-FH100 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic ZS70 and Casio EX-FH100 Cameras
Panasonic ZS70 and Casio EX-FH100 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 Casio EX-FH100 has 102% larger pixel area (2.81µm 2 vs 1.39µm 2 ) compared to Panasonic ZS70, 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 ZS70
or the
Casio EX-FH100 ,
including hyperfocal distance.
