Both Ricoh GR II and Ricoh GR have 16.0 MP resolution sensors but Ricoh GR II's sensor is APS-C (23.7 x 15.7 mm ) and Ricoh GR's sensor is APS-C (23.7 x 15.7 mm ).
Since Ricoh GR's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Ricoh GR II.
Below you can see the GR II and GR sensor size comparison.
Ricoh GR II and Ricoh GR 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.
DxOMark Sensor Scores
Both Ricoh GR II and Ricoh GR 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, GR II has scored 80, 2 points higher than GR.
