Panasonic ZS5 has a
12.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor and features Venus Engine HD II processor. On the other hand, Panasonic ZS25 has a
16.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CMOS sensor .
Below you can see the ZS5 and ZS25 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic ZS5 and Panasonic ZS25 Cameras
Panasonic ZS5 and Panasonic ZS25 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 Panasonic ZS5 has 50% larger pixel area compared to Panasonic ZS25, 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
Panasonic ZS5
or the
Panasonic ZS25 ,
including hyperfocal distance.
