Below you can see the FZ47 and SX600 HS sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic FZ47 and Canon SX600 HS Cameras
Panasonic FZ47 and Canon SX600 HS 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 FZ47
or the
Canon SX600 HS ,
including hyperfocal distance.
