Below you can see the ZS10 and ELPH 510 HS sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic ZS10 and Canon ELPH 510 HS Cameras
Panasonic ZS10 and Canon ELPH 510 HS 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
Panasonic ZS10
or the
Canon ELPH 510 HS ,
including hyperfocal distance.
