Sensor Size and Resolution Comparison image of Samsung HZ30W and Panasonic FZ40 Cameras
Samsung HZ30W and Panasonic FZ40 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
Samsung HZ30W
or the
Panasonic FZ40 ,
including hyperfocal distance.
