Sony A700 has a
12.0MP APS-C (23.5 x 15.6 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 .
Sony A700's sensor provides 6MP more than Konica Minolta 7D's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the A700 and 7D sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A700 and Konica Minolta 7D Cameras
Sony A700 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 Sony A700 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, A700 has scored 66, 8 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
Sony A700
or the
Konica Minolta 7D ,
including hyperfocal distance.
