Panasonic LX7 has a
10.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized CMOS sensor and features Venus Engine 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 LX7 and MX-1 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic LX7 and Pentax MX-1 Cameras
Panasonic LX7 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 Panasonic LX7 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
Both Panasonic LX7 and Pentax MX-1 sensors have been tested by DxoMark. DxoMark 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. Of the two cameras that we are comparing, LX7 has scored 50, 1 points higher than MX-1.

Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Panasonic LX7
or the
Pentax MX-1 ,
including hyperfocal distance.
