Sony HX50V has a
20.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor . On the other hand, Nikon L110 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Expeed C2 processor.
Sony HX50V's sensor provides 8MP more than Nikon L110'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 HX50V and L110 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony HX50V and Nikon L110 Cameras
Sony HX50V and Nikon L110 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 Nikon L110 has 26% larger pixel area (2.34µm 2 vs 1.85µm 2 ) compared to Sony HX50V, 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
Sony HX50V
or the
Nikon L110 ,
including hyperfocal distance.
