Sony A350 has a
14.0MP APS-C (23.6 x 15.8 mm ) sized CCD sensor . On the other hand, Panasonic GF5 has a
12.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features Venus Engine FHD processor.
Below you can see the A350 and GF5 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A350 and Panasonic GF5 Cameras
As seen above, Sony A350 has a 1.7x Larger sensor area than Panasonic GF5. 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
Both Sony A350 and Panasonic GF5 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, A350 has scored 65, 15 points higher than GF5.

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
Sony A350
or the
Panasonic GF5 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(APS-C versus Four Thirds),
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.
