Below you can see the ELPH 340 HS and 5010 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon ELPH 340 HS and Olympus 5010 Cameras
Canon ELPH 340 HS and Olympus 5010 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
Canon ELPH 340 HS
or the
Olympus 5010 ,
including hyperfocal distance.
