Sensor Size and Resolution Comparison image of Casio EX-ZR800 and Panasonic ZS60 Cameras
Casio EX-ZR800 and Panasonic ZS60 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
