Panasonic FP3 has a
14.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor and features Venus Engine IV processor. On the other hand, Sony WX10 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features BIONZ processor.
Below you can see the FP3 and WX10 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic FP3 and Sony WX10 Cameras
Panasonic FP3 and Sony WX10 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 FP3
or the
Sony WX10 ,
including hyperfocal distance.
