Panasonic ZS60 has a
18.0MP (1/2. ) sized CMOS sensor and features Venus Engine processor. On the other hand, Canon A495 has a
10.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Panasonic ZS60's sensor provides 8MP more than Canon A495'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 ZS60 and A495 sensor size comparison.
As seen above, Canon A495 has a infx Larger sensor area than Panasonic ZS60. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
