Ricoh GR II has a
16.0MP APS-C (23.7 x 15.7 mm ) sized CMOS sensor and features GR Engine V processor. On the other hand, Sony A6600 has a
24.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features Bionz X processor.
Sony A6600's sensor provides 8MP more than Ricoh GR II'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 GR II and A6600 sensor size comparison.
Ricoh GR II and Sony A6600 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
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. Ricoh GR II and Sony A6600 sensors have been tested by DxO and the results show that A6600 has a better overall score of 82, 2 points higher compared to GR II's score of 80.
