Sensor Size and Resolution Comparison image of Casio EX-Z33 and Canon ELPH 500 HS Cameras
Casio EX-Z33 and Canon ELPH 500 HS have the same sensor sizes so they will provide same level of control over the depth of field when used with 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
Casio EX-Z33
or the
Canon ELPH 500 HS ,
including hyperfocal distance.
