Panasonic FZ1000 has a
20.0MP 1″ (13.2 x 8.8 mm ) sized CMOS sensor and features Venus Engine processor. On the other hand, Sony A450 has a
14.0MP APS-C (23.4 x 15.6 mm ) sized CMOS sensor and features Bionz processor.
Panasonic FZ1000's sensor provides 6MP more than Sony A450'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 FZ1000 and A450 sensor size comparison.
As seen above, Sony A450 has a 3.1x Larger sensor area than Panasonic FZ1000. 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.
DxOMark Sensor Scores
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Panasonic FZ1000 and Sony A450 sensors have been tested by DxO and the results show that A450 has a better overall score of 66, 2 points higher compared to FZ1000's score of 64.
