Below you can see the FZ60 and HX20V sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic FZ60 and Sony HX20V Cameras
Panasonic FZ60 and Sony HX20V 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
Panasonic FZ60
or the
Sony HX20V ,
including hyperfocal distance.
