Panasonic FH6 has a
14.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Sony WX70 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 FH6 and WX70 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic FH6 and Sony WX70 Cameras
Panasonic FH6 and Sony WX70 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 FH6
or the
Sony WX70 ,
including hyperfocal distance.
