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