Samsung SL102 has a
10.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Panasonic ZS45 has a
16.0MP 1/2.33 (6.08 x 4.56 mm ) sized CMOS sensor .
Panasonic ZS45's sensor provides 6MP more than Samsung SL102's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the SL102 and ZS45 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung SL102 and Panasonic ZS45 Cameras
Samsung SL102 and Panasonic ZS45 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 Samsung SL102 has 59% larger pixel area compared to Panasonic ZS45, 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
Samsung SL102
or the
Panasonic ZS45 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch versus 1/2.33),
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.
