Panasonic FZ70 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor and features Venus Engine processor. On the other hand, Pentax Q10 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor .
Below you can see the FZ70 and Q10 sensor size comparison.
Panasonic FZ70 and Pentax Q10 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 32% larger pixel area (2.34µm2 vs 1.76µm2) compared to Panasonic FZ70, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.
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 FZ70 and Pentax Q10 sensors have been tested by DxO and the results show that Q10 has a better overall score of 49, 8 points higher compared to FZ70's score of 41.
