Below you can see the ELPH 510 HS and FP2 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon ELPH 510 HS and Panasonic FP2 Cameras
Canon ELPH 510 HS and Panasonic FP2 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 510 HS
or the
Panasonic FP2 ,
including hyperfocal distance.
