Olympus SZ-31MR iHS has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features Dual TruePic V processor. On the other hand, Panasonic FP5 has a
14.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor and features Venus Engine IV processor.
Below you can see the SZ-31MR iHS and FP5 sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus SZ-31MR iHS and Panasonic FP5 Cameras
Olympus SZ-31MR iHS and Panasonic FP5 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
Olympus SZ-31MR iHS
or the
Panasonic FP5 ,
including hyperfocal distance.
