Sensor Size and Resolution Comparison image of Olympus FE-4000 and Canon A3200 IS Cameras
Olympus FE-4000 and Canon A3200 IS 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 FE-4000
or the
Canon A3200 IS ,
including hyperfocal distance.
