Panasonic FZ28 has a
10.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor . On the other hand, Nikon 1 V2 has a
14.0MP 1-inch (13.2 x 8.8 mm ) sized CMOS sensor and features Expeed 3A processor.
Below you can see the FZ28 and 1 V2 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic FZ28 and Nikon 1 V2 Cameras
As seen above, Nikon 1 V2 has a 4.2x Larger sensor area than Panasonic FZ28. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
DxOMark Sensor Scores
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It 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. Panasonic FZ28 and Nikon 1 V2 sensors have been tested by DxO and the results show that 1 V2 has a better overall score of 50, 23 points higher compared to FZ28's score of 27.

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 FZ28
or the
Nikon 1 V2 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch versus 1-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.
