Both Panasonic GF8 and Panasonic TS30 have 16.0 MP resolution sensors but Panasonic GF8's sensor is Four Thirds (17.3 x 13 mm ) and Panasonic TS30's sensor is 1/2.3 (6.17 x 4.55 mm ).
Since Panasonic GF8's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Panasonic TS30.
Below you can see the GF8 and TS30 sensor size comparison.

As seen above, Panasonic GF8 has a 8.0x Larger sensor area than Panasonic TS30. 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.
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 GF8
or the
Panasonic TS30 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(Four Thirds versus 1/2.3),
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.
