Canon 1Ds MIII has a
21.0MP Full frame (36 x 24 mm ) sized CMOS sensor . On the other hand, Canon M5 has a
24.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features Digic 7 processor.
Below you can see the 1Ds MIII and M5 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 1Ds MIII and Canon M5 Cameras
As seen above, Canon 1Ds MIII has a 2.6x Larger sensor area than Canon M5. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
DxOMark Sensor Scores
Both Canon 1Ds MIII and Canon M5 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, 1Ds MIII has scored 80, 3 points higher than M5.

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 1Ds MIII
or the
Canon M5 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(Full frame versus APS-C),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
