Panasonic F5 has a
14.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Canon SX240 HS has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features Digic 5 processor.
Below you can see the F5 and SX240 HS sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic F5 and Canon SX240 HS Cameras
Panasonic F5 and Canon SX240 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 F5
or the
Canon SX240 HS ,
including hyperfocal distance.
