12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Digic 4 processor.
Below you can see the FH25 and SX20 IS sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic FH25 and Canon SX20 IS Cameras
Panasonic FH25 and Canon SX20 IS 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 FH25
or the
Canon SX20 IS ,
including hyperfocal distance.
