Samsung HZ35W has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Sony HX300 has a
20.0MP 1/2.3-inch (6.16 x 4.62 mm ) sized BSI-CMOS sensor .
Sony HX300's sensor provides 8MP more than Samsung HZ35W'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 HZ35W and HX300 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung HZ35W and Sony HX300 Cameras
Samsung HZ35W and Sony HX300 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 HZ35W
or the
Sony HX300 ,
including hyperfocal distance.
