Pentax MX-1 has a
12.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized CMOS sensor . On the other hand, Panasonic LX7 has a
10.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized CMOS sensor and features Venus Engine processor.
Below you can see the MX-1 and LX7 sensor size comparison.
Pentax MX-1 and Panasonic LX7 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 Panasonic LX7 has 20% larger pixel area (4.16µm2 vs 3.46µm2) compared to Pentax MX-1, 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. Pentax MX-1 and Panasonic LX7 sensors have been tested by DxO and the results show that LX7 has a better overall score of 50, 1 points higher compared to MX-1's score of 49.
