Canon 40D has a
10.0MP APS-C (22.2 x 14.8 mm ) sized CMOS sensor . On the other hand, Konica Minolta 7D has a
6.0MP APS-C (23.5 x 15.7 mm ) sized CCD sensor .
Below you can see the 40D and 7D sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 40D and Konica Minolta 7D Cameras
As seen above, Konica Minolta 7D has a 1.1x Larger sensor area than Canon 40D. 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 40D and Konica Minolta 7D 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, 40D has scored 64, 6 points higher than 7D.

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 40D
or the
Konica Minolta 7D ,
including hyperfocal distance.
