Both Konica Minolta 5D and Fujifilm S2 Pro 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 5D and S2 Pro sensor size comparison.

Konica Minolta 5D and Fujifilm S2 Pro 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.
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 5D
or the
Fujifilm S2 Pro ,
including hyperfocal distance.
