Samsung HZ50W has a
14.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, 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.
Panasonic ZS70's sensor provides 6MP more than Samsung HZ50W'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 HZ50W and ZS70 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung HZ50W and Panasonic ZS70 Cameras
Samsung HZ50W and Panasonic ZS70 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 HZ50W
or the
Panasonic ZS70 ,
including hyperfocal distance.
