Nikon P7000 has a
10.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized CCD sensor and features Expeed C2 processor. On the other hand, Pentax MX-1 has a
12.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized CMOS sensor .
Below you can see the P7000 and MX-1 sensor size comparison.
Nikon P7000 and Pentax MX-1 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 P7000 has 20% larger pixel area compared to Pentax MX-1, it has potential to collect more light on pixel level hence 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. Nikon P7000 and Pentax MX-1 sensors have been tested by DxO and the results show that MX-1 has a better overall score of 49, 10 points higher compared to P7000's score of 39.
