Sensor Size and Resolution Comparison image of Panasonic ZS60 and Nikon S800c Cameras
Panasonic ZS60 and Nikon S800c 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
Panasonic ZS60
or the
Nikon S800c ,
including hyperfocal distance.
