Kodak Z980 has a
12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Sony WX50 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 Z980 and WX50 sensor size comparison.
Sensor Size and Resolution Comparison image of Kodak Z980 and Sony WX50 Cameras
Kodak Z980 and Sony WX50 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
Kodak Z980
or the
Sony WX50 ,
including hyperfocal distance.
