Canon 6D MII has a
26.0MP Full frame (35.9 x 24 mm ) sized CMOS sensor and features DIGIC 7 processor. On the other hand, Sony A900 has a
25.0MP Full frame (35.9 x 24 mm ) sized CMOS sensor and features Bionz processor.
Below you can see the 6D MII and A900 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 6D MII and Sony A900 Cameras
Canon 6D MII and Sony A900 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. On the other hand, since Sony A900 has 6% larger pixel area (35.33µm 2 vs 33.19µm 2 ) compared to Canon 6D MII, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.
DxOMark Sensor Scores
Both Canon 6D MII and Sony A900 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, 6D MII has scored 85, 6 points higher than A900.

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
Canon 6D MII
or the
Sony A900 ,
including hyperfocal distance.
