Olympus 6020 and Olympus Tough-3000 have the same sensor sizes so they will provide same level of control over the depth of field when used with 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
Olympus 6020
or the
Olympus Tough-3000 ,
including hyperfocal distance.
