Sensor Size and Resolution Comparison image of Olympus 7030 and Fujifilm XP200 Cameras
Olympus 7030 and Fujifilm XP200 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
Olympus 7030
or the
Fujifilm XP200 ,
including hyperfocal distance.
