Panasonic FZ300 has a
12.0MP 1/2.3 (6.17 x 4.55 mm ) sized CMOS sensor and features Venus Engine processor. 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 FZ300 and FZ28 sensor size comparison.

Panasonic FZ300 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.
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 FZ300
or the
Panasonic FZ28 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3 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.
