Sensor Size and Resolution Comparison image of Panasonic FX48 and Olympus VG-160 Cameras
Panasonic FX48 and Olympus VG-160 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 FX48
or the
Olympus VG-160 ,
including hyperfocal distance.
