Canon 6D has a
20.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Digic 5+ processor. On the other hand, Canon 1Ds MIII has a
21.0MP Full frame (36 x 24 mm ) sized CMOS sensor .
Below you can see the 6D and 1Ds MIII sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 6D and Canon 1Ds MIII Cameras
Canon 6D and Canon 1Ds MIII 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 6D and Canon 1Ds MIII 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 has scored 82, 2 points higher than 1Ds MIII.

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
or the
Canon 1Ds MIII ,
including hyperfocal distance.
