Panasonic ZS50 has a
12.0MP (6.17 x 4.55 mm ) sized CMOS sensor . On the other hand, Panasonic FZ28 has a
10.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor .
Below you can see the ZS50 and FZ28 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic ZS50 and Panasonic FZ28 Cameras
Panasonic ZS50 and Panasonic FZ28 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.
DxOMark Sensor Scores
Both Panasonic ZS50 and Panasonic FZ28 sensors have been tested by DxoMark. DxoMark scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Of the two cameras that we are comparing, ZS50 has scored 44, 17 points higher than FZ28.

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 ZS50
or the
Panasonic FZ28 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
( versus 1/2.3-inch),
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.
