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, Canon 10D has a
6.0MP APS-C (22.7 x 15.1 mm ) sized CMOS sensor .
Ricoh GR II's sensor provides 10MP more than Canon 10D'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 10D sensor size comparison.
Sensor Size and Resolution Comparison image of Ricoh GR II and Canon 10D Cameras
Ricoh GR II and Canon 10D 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 Ricoh GR II and Canon 10D 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, 23 points higher than 10D.

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
Ricoh GR II
or the
Canon 10D ,
including hyperfocal distance.
