Canon M6 has a
24.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features Digic 7 processor. On the other hand, Pentax K-7 has a
15.0MP APS-C (23.4 x 15.6 mm ) sized CMOS sensor and features Prime II processor.
Canon M6's sensor provides 9MP more than Pentax K-7's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the M6 and K-7 sensor size comparison.
Canon M6 and Pentax K-7 have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
DxOMark Sensor Scores
Both Canon M6 and Pentax K-7 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, M6 has scored 78, 17 points higher than K-7.
