Nikon 1 J3 has a
14.0MP 1-inch (13.2 x 8.8 mm ) sized CMOS sensor . On the other hand, Nikon 1 S1 has a
10.0MP 1-inch (13.2 x 8.8 mm ) sized CMOS sensor .
Below you can see the 1 J3 and 1 S1 sensor size comparison.
Nikon 1 J3 and Nikon 1 S1 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 1 S1 has 41% larger pixel area (11.57µm2 vs 8.20µm2) compared to Nikon 1 J3, 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. Nikon 1 J3 and Nikon 1 S1 sensors have been tested by DxO and the results show that 1 S1 has a better overall score of 56, 4 points higher compared to 1 J3's score of 52.
