Below you can see the FH27 and W530 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic FH27 and Sony W530 Cameras
Panasonic FH27 and Sony W530 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 FH27
or the
Sony W530 ,
including hyperfocal distance.
