Both Panasonic ZS25 and Kodak AZ528 have 16.0 MP resolution sensors but Panasonic ZS25's sensor is 1/2.3-inch (6.08 x 4.56 mm ) and Kodak AZ528's sensor is 1/2.3 (6.17 x 4.55 mm ).
Since Kodak AZ528's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Panasonic ZS25.
Below you can see the ZS25 and AZ528 sensor size comparison.

Panasonic ZS25 and Kodak AZ528 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 ZS25
or the
Kodak AZ528 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch versus 1/2.3),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
