Kodak Z980 has a
12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Panasonic SZ5 has a
14.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor .
Below you can see the Z980 and SZ5 sensor size comparison.
Sensor Size and Resolution Comparison image of Kodak Z980 and Panasonic SZ5 Cameras
Kodak Z980 and Panasonic SZ5 have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since Kodak Z980 has 16% larger pixel area compared to Panasonic SZ5, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
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
Panasonic SZ5 ,
including hyperfocal distance.
