Konica Minolta 7D has a
6.0MP APS-C (23.5 x 15.7 mm ) sized CCD sensor . On the other hand, Sony A100 has a
10.0MP APS-C (23.6 x 15.8 mm ) sized CCD sensor .
Below you can see the 7D and A100 sensor size comparison.
Sensor Size and Resolution Comparison image of Konica Minolta 7D and Sony A100 Cameras
Konica Minolta 7D and Sony A100 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
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It 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. Konica Minolta 7D and Sony A100 sensors have been tested by DxO and the results show that A100 has a better overall score of 61, 3 points higher compared to 7D's score of 58.

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
Konica Minolta 7D
or the
Sony A100 ,
including hyperfocal distance.
