Panasonic ZS50 has a
12.0MP (6.17 x 4.55 mm ) sized CMOS sensor . On the other hand, Sony A450 has a
14.0MP APS-C (23.4 x 15.6 mm ) sized CMOS sensor and features Bionz processor.
Below you can see the ZS50 and A450 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic ZS50 and Sony A450 Cameras
As seen above, Sony A450 has a 13.0x Larger sensor area than Panasonic ZS50. 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 ZS50 and Sony A450 sensors have been tested by DxO and the results show that A450 has a better overall score of 66, 22 points higher compared to ZS50's score of 44.

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
Sony A450 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
( versus APS-C),
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.
