Below you can see the 5010 and WX150 sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus 5010 and Sony WX150 Cameras
Olympus 5010 and Sony WX150 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 5010
or the
Sony WX150 ,
including hyperfocal distance.
