Below you can see the HX200V and FZ60 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony HX200V and Panasonic FZ60 Cameras
Sony HX200V and Panasonic FZ60 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
Sony HX200V
or the
Panasonic FZ60 ,
including hyperfocal distance.
