Pentax Q10 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor . On the other hand, Sony WX350 has a
18.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor .
Sony WX350's sensor provides 6MP more than Pentax Q10'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 Q10 and WX350 sensor size comparison.
Sensor Size and Resolution Comparison image of Pentax Q10 and Sony WX350 Cameras
Pentax Q10 and Sony WX350 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 Pentax Q10 has 49% larger pixel area compared to Sony WX350, it has potential to collect more light on pixel level hence 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
Pentax Q10
or the
Sony WX350 ,
including hyperfocal distance.
