Sony A9 II has a
24.0MP Full frame (35.6 x 23.8 mm ) sized Stacked BSI-CMOS sensor and features BIONZ X processor. On the other hand, Canon R6 has a
20.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Digic X processor.
Below you can see the A9 Mark II and R6 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A9 II and Canon R6 Cameras
Sony A9 II and Canon R6 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 Sony A9 II and Canon R6 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, A9 Mark II has scored 93, 3 points higher than R6.

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
Sony A9 II
or the
Canon R6 ,
including hyperfocal distance.
