Sensor Size and Resolution Comparison image of Casio EX-ZS15 and Olympus 7010 Cameras
Casio EX-ZS15 and Olympus 7010 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
Casio EX-ZS15
or the
Olympus 7010 ,
including hyperfocal distance.
