Both Sony ZV-1F and Panasonic GX8 have 20.0 MP resolution sensors but Sony ZV-1F's sensor is 1″ (13.2 x 8.8 mm ) and Panasonic GX8's sensor is Four Thirds (17.3 x 13 mm ).
Since Panasonic GX8'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 Sony ZV-1F.
Below you can see the ZV-1F and GX8 sensor size comparison.

As seen above, Panasonic GX8 has a 1.9x Larger sensor area than Sony ZV-1F. 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
Sony ZV-1F
or the
Panasonic GX8 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1″ 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.
