Both Fujifilm S3 Pro and Konica Minolta 7D have APS-C sized 6.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the S3 Pro and 7D sensor size comparison.
Sensor Size and Resolution Comparison image of Fujifilm S3 Pro and Konica Minolta 7D Cameras
Fujifilm S3 Pro and Konica Minolta 7D 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 Fujifilm S3 Pro 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, S3 Pro has scored 60, 2 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
Fujifilm S3 Pro
or the
Konica Minolta 7D ,
including hyperfocal distance.
