Both Canon 4000D and Canon 650D have 18.0 MP resolution sensors but Canon 4000D's sensor is APS-C (22.3 x 14.9 mm ) and Canon 650D's sensor is APS-C (22.3 x 14.9 mm ).
Since Canon 650D'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 Canon 4000D.
Below you can see the 4000D and 650D sensor size comparison.
Canon 4000D and Canon 650D 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 Canon 4000D and Canon 650D 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, 4000D has scored 63, 1 points higher than 650D.
