Sensor Size and Resolution Comparison image of Canon ELPH 500 HS and Casio EX-Z33 Cameras
Canon ELPH 500 HS and Casio EX-Z33 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
Canon ELPH 500 HS
or the
Casio EX-Z33 ,
including hyperfocal distance.
