Fujifilm XP150 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor . On the other hand, Sony HX50V has a
20.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor .
Sony HX50V's sensor provides 6MP more than Fujifilm XP150'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 XP150 and HX50V sensor size comparison.
Sensor Size and Resolution Comparison image of Fujifilm XP150 and Sony HX50V Cameras
Fujifilm XP150 and Sony HX50V 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.
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
Fujifilm XP150
or the
Sony HX50V ,
including hyperfocal distance.
