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